I had tried three or four bargain fan speed controllers from eBay and radio shack and none of them were near adequate. I finally bit the bullet and bought a pair of Dew Buster fan speed controllers and have not regretted it a bit. Installation is easy and the rheostats have the proper range to vary the fan speed from a blast for cooling to a gentle breeze for boundary layer disruption. The cost notwithstanding these are the only controllers that I have found that work appropriately with fans on a dob. They are emphatically recommended. I just purchased my third unit

After many years of no problems with it I accidentally broke the cigarette lighter plug on my DewBuster. After I ordered a new one from Ron he checked his records and offered to replace the plug on my existing one and refund me the difference. Which he did within a week. What great service for a great product. Thanks Ron.

From the solid, crinkle-finish metal box to the silky-smooth rheostat, the DewBuster is 1st Class all the way. You can find cheaper, but you'll never find better. Especially these days, quality doesn't cost, it pays. And the quality is appreciated long after the price is forgotten.

Hi Ron, Just wanted to let you know my Dew Buster is now over 9 years old, and still running perfect! I use it on a 120mm refractor usually with four Heater strip. Very glad I bought this product instead of some cheaper unit. I noticed the new ones have a lot more ports that mine, but I have no complaints! Thanks for producing a superior product!

Although I haven't had my DewBuster Controller for long, its performance to date has been incredible. I live in Orlando, FL where high humidity and heavy dew formation are the norm. Before I bought my DewBuster I just had a dew shield and dew formed on my Celestron NexStar Evolution 6 SCT after only 30 minutes or so. Since installing the DewBuster and Dew-Not heater strips I've had no dew formation at all. I went for massive battery-capacity overkill (a friend sold me a decommissioned 92 amp-hour deep-cycle UPS battery for next to nothing) and expect the DewBuster's low power consumption will help this battery last for years. This review wouldn't be complete without raves for Ron's customer support. Not only does he have tons of great information on his website, he provides great individual technical support as well. He emailed me detailed customized information to help with the setup and troubleshooting of my dew prevention system. I highly recommend DewBuster!

Purchased my unit in August 2014. The summer of 2014 is the first time in quite a few years that I have had dew form on my SCT corrector plate in only 1 hour, even while using a dew shield (I live in Southeastern PA). I decided it was time for active dew control. Being an Electrical Engineer, I researched the available dew control devices out there. The DewBuster was exactly what I was thinking about building myself before I discovered it. Temperature differential feedback control is the way to go. No guessing what the temperature setting should be. The cost of the parts in small quantities, the development time and effort of putting it in a nice package, outweighed my desire to build it myself and get back under the stars as soon as possible. I have used it many times since last August. The quality of the unit and simplicity is unsurpassed. Nothing to do but turn it on and set if for 5 degrees differential(in my usage experience). I use the medium voltage outputs for the finder scope objective, the finder scope eyepiece and the main eyepiece as well as one to heat the eyepieces in my accessory tray. The DewBuster makes it so easy. It's just not something I have to think about anymore.

I sent my DewBuster to Ron for modification (new power cord options). The Postal Service lost my DewBuster on the return trip. Tracking info shows it made it to the New Orleans sorting center and never left there. Ron provided me a new DewBuster free of charge and shipped it to me for free. Now, Ron didn't have to do this. He didn't lose my DewBuster- the Postal Service did. So, here we have a superior product backed up with exemplary (and increasingly rare) customer service. Ron, WELL DONE, and THANKS!

This the second Dewbuster I have purchased within a year. Suffice to say, I would not have bought another if I didn't feel Dewbuster was the best product of it's kind available. There are so many reasons I like this product, among them: quality, durability, efficient power consumption and an excellent warranty. In my experience, Dewbuster sets the standard for dew prevention devices.

Never before have I had such an ability to customize and tailor an astronomy product to exactly fit my needs and wants. The DewBuster incorporates a high degree of design and intelligence. To such a degree, in fact, it is stunningly simple to use. Just one dial for temp-delta, that’s it. In my case, I have one additional switch to turn on/off the 12V power outputs. Workmanship is extremely solid and well outfitted for form and function. Ability to customize is beyond anything I have ever experienced. This was customer service as it was meant to be. I found Ron very knowledgeable and helpful. Astronomy products are not expensive if you only buy what you will keep forever!

I did my research, and found the DewBuster highly regarded amongst the community, placed my order and not long after I received my unit. Extremely happy with the build quality. The effectiveness of the DewBuster was almost immediately realised on my first use, and reaffirmed every use after. There have been quite a number of nights where I've been imaging away only to notice while packing up that dew has formed on various accessories stored away from the scope and even on the mount itself.. The dreaded thought crosses ones mind that the night of imaging has ruined by dew, however upon inspecting the glass I always find they're crystal clear. I know that if I didn't have the DewBuster most of those imaging nights would have simply been ruined. Extremely easy to use, fantastic design, rugged and great on power consumption. I highly recommend the DewBuster controller & temp sensors.

Last weekend I went to the Almost Heaven Star Party at Spruce Knob WV. Due to Hurricane Irene, only the last night was clear. However it rained extensively during the day, and the fields never dried out. A bank of fog rolled in at dusk and then cleared. Virtually everything was soaked with dew: my laptop, my table, my tripod, even the inside of my (unheated) dew shield eventually got wet. BUT, the optics on my 11" SCT stayed bone dry thanks to the Dewbuster. I was really worried because I thought the 11" corrector plate would really be a challenge to keep clear, but the setup worked great. This was my first real experience using the Dewbuster and I didn't want to take any chances, so I cranked it up a bit higher than necessary, then lowered it as the night went on. It kept up fine. Although we only had one night, thanks to the Dewbuster, the observing was great at this rare, dark site on the east coast. . What a great product!

I have the Dewbuster connected to an AstroZap and have ZERO dew related issues with viewing. The DewBuster is an excellent product. My email questions were quickly and accurately answered. I HIGHLY recommend the DewBuster. My scope is a Celestron CPC 800 GPS XLT. You definitely need dew control products for this type of scope. In addtion to the optical tube, I also use the DewBuster to power an eyepiece heater and a Telrad finder. Works great.

Great product! Easy to use and the simple and intuitive "ambient temperature plus X degrees" has eliminated dew without creating the blurring thermals that can occur in the OTA from overheating.

I received my DewBuster yesterday and was able to put it to the test last night. What a wonderful piece of engineering and craftsmanship! One cannot really understand the differences in this and the other offerings until you see it in person. From the moment I placed it in my hands, I could see it was a solid, high quality piece of gear. And, it works beautifully, too. It appears I can stay dew free (and I live in the humid South, too) while using much less battery power than before with the off-the-shelf controller. Great piece of gear!

I have owned other dew controllers in the past; I won't mention the brands, but I can tell you about their performance with respect to the Dew Buster. I just received it today and I have to say that I was immediately impressed with the overall appearance and the quality of work. This controller will literally last a lifetime; there's no comparison with any of the others. This is simply one of the highest quality accessories I have ever owned, and it's been customized according to MY needs! One of the things I absolutely hated about the others that I've owned is the fact that the RCA jacks are recessed into the body of the controller, with the only attachment being on the circuit board. Even after just a few observing sessions, I could feel that the jacks were loosening up and if I wasn't careful, I'd have a real problem on my hands. Not only that, the plastic controller box would easily fall apart in a couple of years, if not sooner. Well, I don't have to worry about that anymore; the DB circuit board is encased in a high-quality, light-weight metal that will last for decades and the RCA jacks are case-mounted, preventing any stress from reaching the connections on the circuit board. This controller is well-suited to perform perfectly in ANY environment. Patrick Wayne, TAAS

Tonight was the first time I was able to use it; I just came back inside because the clouds started rolling in. All I had to do after hooking all of the heaters strips up to the DB, was turn the dial on the front to a setting around 5, or 6. The temperature-controlled outlet on the right side was hooked up to the strip on my SV80ST's lens cell, just behind the dew shield. I had my other strips hooked into the medium power outlets for my EPs and diagonal. The temperature controlled outlet started working AFTER it had been on there a while; before you take that sentence out of context, let me explain. There was no need for it to turn on because the OTA was already at equilibrium and it didn't need any heat until about an hour later. I think that's also one of the coolest features of the DB. It really is a set-and-forget dew controller. Turn one knob to the desired setting and observe away, the DB takes care of everything. I was only outside for a little while, but after only 5 minutes I was able to observe; the views were picture-perfect and sharp, I had no dew, fogging up of the OTA, or any problem at the EP. The DB performed flawlessly and I honestly forgot about it until I broke everything down. Believe me when I say that this accessory is a MUST-HAVE and the BEST dew controller on the market, period. I guarantee you that Ron's work is worth 4 times as much as he's asking for the DB, not only that, but he will customize it for you, according to your needs and desires. No other company on the planet can take care of you the way he can. And don't get me started on his warranty! He guarantee's his work for 2 years, even if you use home-made heaters, or any other brand heater, other companies will only honor a one year time period for their warranties. He will also honor a "good faith" policy after the 2 year time-frame. Try to show me a competitor willing to do that; that in and of itself is proof that the DB is right for you. I cannot stress how good this dew controller is, you will NOT be disappointed and I bet once you have the chance to check it out, it will become a permanent addition to your Astronomy equipment.

I built dew heaters for two 3" refractors and a 9.25 inch SCT following the plans on the Dewbuster website. These are mounted permanently on the scopes. Doing photography requires two scopes to be kept from dewing. The Dewbuster has done its job well so far in the extremely humid conditions of the Puget Sound area. The build of the product feels solid and Ron's warranty and repair terms are generous. Highly recommended.

I am most happy with your product and recommend it everyone who does not have a dew system. It is used in the Houston, Texas area where we continually have high humidity and dew is almost always the limiting factor when viewing. I have been able to enjoy many more hours of viewing than others around me who had to call it a night because of dew. My time is valuable and it is money well spent on your product for the additional time I am able to enjoy my hobby. Not one time have I had any problems with dew since using your controller. Your product is professionally made and of the highest quality one could expect. Please fill free to use this endorsement of your product. I hope in the future you manufacture dew strips of the same quality as your controller.

I can not imagine having an SCT telescope without a DewBuster here in FL. I used to struggle with a homemade dew shield and a hair dryer when I had a NexStar 5. Those things didn't work at all really when I upgraded to a CPC800. The DewBuster removed all that fuss. I'm going to get a second one when I get my CPC1100. I broke the sensor on my current unit and Ron made it right in a couple of days and it wasn't even his fault or the fault of the product. There aren't enough "stars" in this rating system for me to tell you how thoroughly satisfied I am with Ron's DewBuster.

Waited till there was some very heavy dew in the Northern Virginia area before writing this. The dewbuster worked perfectly in keeping my newtonian secondary clear of dew. The controls are very simple to use and the power consumption was far less than I expected - my batteries were still in good shape after a long night. I like the large number of outputs available - and heaters can be added anytime during the night. I used dew-not heaters and they worked great. The thermocouple on the secondary was also easy to install. I also appreciate the website providing a lot of information on making dew heaters. The supplied 300 ohm resistors were easily soldered to make a nice dew heater for my secondary. Only improvement - I need is a bracket to mount the Dewbuster solidly to my tube - its on with some tape at the moment. In conclusion - I like a robust product I can rely on that takes no effort to get exact control of dew. I am already recommending this to my friends who were struggling with controlling dew on SCTs using other more basic controllers.

Ron is a great guy and helped me out with setting up my new CPC 800 XLT he definitely knows his telescope hardware/software, Culmination skills, and has excellent electro mechanical skills. I had used the Dewbuster on 2 different scopes so far (EXT 125mm Mead and my Trusty Celestron CPC) it has worked well on them both. Ron not only manufactures FANTASTIC, problem solving, products that are well documented and easy to use but he also stands behind his product 100% and is very knowledgeable and active in astronomy club matters. You can tell he loves Astronomy and seems he was always more than willing to help newbys in the club and promote Astronomy with his many years of experience/knowledge. My Dewbuster had a slight problem with the leds not flashing correctly or up to Ron's high standards. I was unaware it had a problem as it was keeping the dew off but Ron saw the lights acting a bit strangely at an Astronomy field event we both frequented a few years back. He took the unit , repaired it 100%, and mailed it back to my home within a few days. It has worked great so far now that I am more familiar with the blinking lamps. Things happen (murphies law) but Ron provided Excellent customer support. :) I think I can say that as I am in the electronics profession myself and rarely do you get this level of expert service and knowledge on consumer electronics products that may cost many of hundreds or thousands $$$ more. The DewBuster works great is economical, convenient, and keeps the Dew off my equipment. It works easily and efficiently. It also has room to put quite a few extra heating elements on it (very expandable) compared to competitor models I have researched. The construction is tough as nails and well designed so I expect it will function 100% for many years. I can sell a few telescopes but I am hanging on to my Dewbuster for the next scope :) Ron provides great service, knowledge, Excellent Product and help if you need it. This is rare as some manufactures of (very) high priced equipment in the astronomy and other technical fields do not offer this same level of customer support for extremely expensive products and often leave the poor customer wondering or hanging thinking: Why did I buy off that Distributor or company ??? We all been there - most of us anyhow :) My DewBuster means no more hair dryers ever in the back yard as the neighbors looking at me strangely when I used to dry out my scopes :) Thanks so much Ron for your unique products and excellent service. DewBuster is Highly recommended by me. The Dew here in La is heavy most of the time and the Dewbuster cures that Astronomical problem. Tom McManus, Covington, La.

I have had ONE problem with my DewBuster, Ron not only took it in way after the warranty had expired, he upgraded my DewBuster for free. That's service!!!! I use mine on a 10" Meade LX-200, I have never had a bit of dew on my lenses, even down here in the southeast. I would recommend the DewBuster to anyone.

After years of observing with a 10 inch Newtonian, I switched to an 11 inch Celestron. I immediately became acquainted with the effects of dew on an SCT. The Dewbuster was one of my first and best accessory purchases. It has worked flawlessly for over four years.

My C14 has been plagued with severe corrector plate dewing ever since I first bought it in 1988. I have tried three different dew prevention devices through the years and all of them never really prevented dew from forming. In conjunction with a dew cap, dew had only been held at bay for a while at best. This has been especially frustrating during long CCD imaging when interruptions ruin difficult to set up exposures. Then I decided to try DewBuster. In a nutshell, it works PERFECTLY!!! Dew has been relegated to history for my C14. Equally important to note is that the temperature difference between the ambient air temperature and corrector plate are tunable only just far enough to prevent dew but not too much to cause thermal tube currents or distort the critical figure of the corrector so that even high resolution planetary imaging can still be performed with out worry. Hat off and many thanks to Ron for making this superb product available!

Nothing was more frustrating than hauling my LX200R to dark skies and setting up, only to have condensation problems send me right back home. DewBuster solved that issue and has allowed me to have many awesome observing sessions. It is surely the best accessory I have purchased for my system and the one I cannot do without. I use one on the optical tube and one at the eyepiece and the performance is outstanding. I have owned my DewBuster for over four years and have had no trouble at all. The DewBuster should be the first accessory you purchase... you will not be disappointed.

Do you see all those 5 star ratings? That's not Ron being selective with which testimonial ratings he displays on his site. That's a 100% statistically representative sample of what people think of Ron and his product. I reckon the one or two 4 star ratings were accidents when submitting the Testimonial forms 8-) Ron makes the most functional Dew Controller on the Market. The most reliable on the market. The Best Value on the market. For what it can do compared to the competition it is an absolute bargain! I've learned the hard way when buying cheaper alternatives to all sorts of astro gear, that you really do get what you pay for. Ron's Dewbuster is worth every extra cent. As for his customer service. There's very few in the entire US Astro Community that can rival him for CS. In fact I'd put him at the top of the list that includes John Marstiller of DewNot, Ron Newman of Moonlite, Gary Myers of Servocat and the legendary Howie Glatter. I had very specific requirements and Ron helped me sort out my custom spec. The amount of time he devoted to answering my questions via email went way above and beyond the call of duty. I must have asked 10 questions per email and sent about 12 emails. Ron answered every question in every email within a couple of hours of me sending them. The level of pre-sales and after sales customer service he provides is extraordinary. My Dewbuster is at the heart of my heavily modded scope. Its temp sensor output powers my secondary heater. It has 7 medium power heater outputs and yes, I am actually using all of them. It has a 3v output to power my Green Laser Pointer and last but not least it has 4 12v outputs to power other devices. So basically it is my Dew Controller, Power distribution block and Battery level indicator/protector in one unit!! I call it the Flux Capacitor!! You'll see why if you look here 8-) www.flickr.com/photos/ca1ibos/sets/72157621900605125

Brilliant piece of equipment. It just works, and in damp Wales we get a lot of dew! Plenty of sockets to add additional heaters for eyepieces, Meade hand control etc. Since fitting it the only problems I've had with dew were from a misplaced dew-heater. I bought this when the UK pound bought nearly two dollars but I'd buy it again even with the current poor exchange rate.

Awesome device for my 12" LX200GPS. Never once had a problem with dew since the install of the system (scope and eyepiece). Here in the Northwest the nights are very damp and the car has enough dew on it to support life on Mars... telescope is totally clear of dew, simply amazing!!

I purchased this unit based of the recommendation of Cloudy Night forum members. I am very pleased with it. It is keeping my dual imaging setup - TSA102 with ZS80FD as guide scope - dew free and, most important, it is very easy to use. The same is true for my C8. The corrector plate doesn't even know what dew is. On top of that, Ron is a very kind and helpful person. After receiving my DewBuster, I thought about converting two ports so that I could use them as 12 volt plugs. Ron sent me all the info, with images, what I had to do - some cutting and soldering. Everything worked out like a charm. I can really recommend this "anti dew system" to anybody. It is a great product!!!

I've never used any other form of dew control, so I am unable to offer any comparative comments, but this piece of equipment sure does work and it has already saved me money. Early one morning, and in a very tired state, I forgot to shut down the Dew Buster and only remembered the following weekend. No worries. The unit had shut itself down and I was able to recharge my portable power pack without problem. Any other system would have cost me a new power pack. *** Top marks Ron! ***

I live in Salt Lake City Utah and we get get our share of dew (Weather I'm in the mountains or the desert) which can leave your scope a soggy or frozen mess and end your evening! We do have our unbelievably dry nights too, but when the humidity is high I use my Dew Buster and end my problems and enjoy observing when ordinarily I might have gave up! I use a battery jump starter to power up my LX200 12" and the Dew Buster is powered from it also and I can make it all night with no issue's! It pays to be flexible relative to your local environmental situation and with Dew Buster you can be!

I bought my DewBuster in used condition from a third party. I had some strange behavior from it and heard that Ron Keating was present at that star party. I summoned him over to look at it. He asked me to leave it with him before he returned home and he would take care of the problem and asked only that I pay him for the return shipping. Considering that I neither purchased the unit directly from him, nor was it within the warranty period, I rate this as truly outstanding customer service.

Since I purchased my DewBuster nearly three years ago, it has been rock solid and is a very important part of my Astro-Imaging setup. I live in the south where moisture and humidity are a constant problem and the DewBuster has been instrumental in keeping both my gear and optics dry while taking beautiful images of our night sky.

I live near Savannah, GA. The humidity is usually very high and dew forms very quickly. For example, I was observing a month ago. Everything, including my observing notes and accessory cases, was totally wet very quickly, except the corrector lens on my 8" SCT remained absolutely clear. I could continue to observe for three hours thanks to my Dewbuster (and the Astrozap wired dewshield).

Took a while for me to nut out the effectiveness. Now its a matter of powering it up & forgetting about it. Not discounting the battery charge either. Sydney Australia is where a greater percentage of my observing happens. Dewbuster without a doubt prolongs the viewing but by the same token lessens the amount of sleep that follows!

It was frustrating to get my 8" SCT (with dew shield) setup and aligned, only to have the evening cut short by dew. Up here in New England it's hard enough to find clear nights for viewing without fighting dew on top of it. The DewBuster has solved that problem - in fact the only time I've had dew problems since I purchased it was when I didn't set it high enough while on vacation in the NH White Mountains. But after cranking the controller up to full blast the 'scope cleared up in a few minutes. Learning to use the DewBuster has been very easy - in the dark, no less. It is very easy on my battery pack too - I figured my viewing sessions would be shortened by the DewBuster's battery draw, but I have yet to drain the battery in a single evening with both the telescope and DewBuster running simultaneously. The LED indicators are simplicity itself - a quick glance tells you what's happening with the electronics. The quality of the device seems quite high - very rugged - and the cables are long enough to allow full rotation and then some of the mount. Hats off to Ron Keating for proving that "Made in the USA" can still be done, and done well.

My home is located in a river valley, adjoining a lake, in Central Illinois, so we have frequent extreme humidity and heavy dewing. I have found that the DewBuster controller can adapt to all conditions, with minimal image degradation, even under severe locations. I use it on an 8" SCT.

I wish all my astronomy equipment was as well engineered and built!! I am a member of the Astronomy Club of Akron, Ohio. I have a Celestron CPC-11. In my climate, heavy duty dewbusting is a must. With an 11" tube, I would be good for 30 minutes without the Dewbuster. The first controller I had was from another well known brand. It caught on fire when it was only 12 months old. That is when I purchased the Dewbuster on the advice of a fellow astronomer. It is GREAT! There are now about four Dewbusters in our club and everyone else wished they had one.

Ron gave me excellent suggestions of exactly what I needed and then he made me a custom DewBuster controller for a very very reasonable price. It has been very helpful to have access all of the 8 plug-ins that I needed for my set-up. When I installed the electrical connections under my deck I damaged an inside capacitor in the plug-in and Ron was very generous to send me out a replacement part without any charge - even though I was the one that caused the damage. This is really much more than excellent customer service. I have never had ANY dew problems since I installed the DewBuster here in southern California - and this is the MOST important thing. I also had DewNot heaters made for my set-up and I would also recommend this company for any needed heaters - as they were very reasonably priced and that company was also willing to make me several custom straps including some double-lined units for my binocular viewer and also for my regular binoculars. I previously had the Kendrick Controller, and the DewBuster is a MUCH superior product and just better and of a much higher quality. The great service coupled with the excellent quality and functionality of the controller earns the DewBuster my very highest recommendation.

Great product, great customer support! I had Ron add a couple of 12V convenience outlets to mine as well as lengthening the cable to 10 feet, and he also increase the gauge of the wire to compensate for the extra length. Now I use it for my power distribution center on the scope as well as dew control and I only need one power cord. The fact that it has probes to measure the scope temperature AND the air temperature means that it will use as little power as possible to keep your optics dew free. Unlike other controllers where the knob sets a power level, the knob on the DewBuster sets the temperature difference between the two probes. The electronics then feeds just enough power to the heater strips to maintain this difference. As conditions change during the night, you don't have to reset your power level. You just set it and forget it, and concentrate on viewing instead of dewing!

If you've lost precious observing opportunities to fogged, dewy or iced optics, the DewBuster is your silver bullet. Buy the 'Buster and find something else to worry about, because those problems will be history. My scope's a 12" Lightbridge truss-tube dobsonian formerly plagued with fogged eyepieces/red-dot finder and dewy/iced secondary mirror. I purchased the DewBuster w/Dobsonian sensor option and resistors from Ron, built heaters for eyepiece, finder and secondary using the on-line instructions and haven't lost a moment of observing time to condensed atmospheric moisture since. I observe in widely varied conditions (from >90 degrees F & >90% humidity to 12 degrees F) for extended periods using a single 5Ah battery; the 'Buster parses electrons to heaters like a miser. I have yet to exhaust the battery despite observing for over 4 hrs. in below freezing temps. Prior to ordering, I emailed Ron with configuration questions specific to my scope. He answered my inquiry personally and promptly and provided excellent recommendations; this guy knows his stuff and cares about his product and customers. Delivery occurred on schedule and shipping information was communicated promptly via email. The build quality of the controller is very professional: high quality metal enclosure, durable finish and markings, low luminosity red LED operational indicators. Operation is simple: set the single dial to the appropriate degrees above ambient air temp and observe. I can't say enough about this product and the entrepreneur who produces/supports it. If there was a rating above Excellent, I'd use it. 6 STARS - Superlative!

Mike Borman Evansville Astronomical Society Evansville, Indiana www.mborman.org I have two Dewbusters, one for my telescope mount at home and one for use in the field at star parties.

After retirement I decided to pursue astronomy as a hobby and spent considerable time researching essential and "best bang for your buck" items. The Dewbuster is both. I initially tried viewing without dew control and quickly found it a real problem. The Dewbuster seemed like a clever improvement over the standard controllers, and indeed it is. To quote one television pitchman, "Just set it and forget it." Easy to set up, easy to adjust, well made and rugged, the Dewbuster is exactly what Ron Keating says it is. Good work, Ron.

This piece of equipment is rock solid performance--period. Install it, set it, and forget it. And that is what I have done. Whether dew is imminent or not, it is always protecting my optics and it has not faltered. Ron has first rate service answering all questions before the sale. I suspect any repair service will be top notch also--though probably rarely needed. Thank you Ron for producing such a superb, quality product...

When setting up my current dual scope platform I consulted Ron about the needed power and mechanical setup. His service was over the top. He designed a wiring harness for both scopes and suggested settings to work from for the refractor and SCT. By far the best service I've ever received from any vendor (well maybe a tie with Astro-Physics ;-) ).

Went to my first star party in 2002 and after 1 hour my eyepieces and mirrors were completely covered in dew. The nightly sounds of crickets and frogs were soon replaced by hair driers running across the field. When I got home the first thing I did was to look into getting a Dew Buster. Best decision I ever made. Now I do not have to worry about Dew. The system is easy to use and hook up and the ambient temp dial is great for combating due without heating your optics too much. Also look into www.dew-not.com for heater strips.

William Mckinstry Donaghadee Northern Ireland Even for a novice like myself I found the controller easy to set up and easy to use, it does a perfect job, from instructions you can download from the site it even gives help for the different times of the year and how to prevent dew forming on the inside when moving a scope to and from from the house to the outdoors and back inside again.

I have been using the Dew Buster for several years in Wisconsin weather, and have never had a problem with it, as it is well built. It works as advertised and is good value for the money. I also have a pricey Kendrick heater, but only bought it because it can be computer controlled which I needed for my remote observatory. All in all, I would buy another Dew Buster if I needed it and whole heartedly recommend this product.

I have had my DewBuster since Sept 2003. It spends 99% of its time in my observatory which is operated remotely. It powers up when the observatory comes on line and I really don't ever think about it. It just plain works. I am using Kendrick heaters strips and never have any dew issues. I have modified the power cord on my unit so it uses a quick disconnect connector. This configuration allows it to be easily removed from the observatory for used on a scope in the field when needed without having to disturb the wiring harness in the observatory. I just wish the option to specify the number of temperature controlled port was available back when I purchased my unit. Overall, it's well built and simple to use. I see no reason this thing shouldn't out live me.

I struggled with dew for the better part of three decades since I began using SCTs. I tried everything. Hairdriers. Primitive heater strips. The Kendrick System when it came out. I was never able to completely banish the curse of the wet corrector, though, until I started using the DewBuster. Not only does it keep my optics dry, it does that while consuming a minimum of battery power. How would I sum up my opinion of the DewBuster? Easy: JUST GET ONE!

Absolutely a great product. With the purchase of a C14 I figured it was time to replace the cheap cigarette lighter controllers I'd been using. A C14 has a huge dew strip for the OTA not to mention powering regular heaters for eyepieces etc. A cheap non-pulsed cigarette controller on a C14 would either knock a battery down in no time or overheat. I started looking into thermostatically controlled and pulse controllers. What caught my initial attention with the DewBuster is that the website is the most informative on understanding dew and how to combat it. Ron has taken the time not only to explain the product, but the problem it solves. I contacted Ron to ask some questions and his customer service was excellent. Since I use the C14 in the field as well as in my observatory Ron made up an extra cable for me, one for a deep cycle battery and one for the observatory. The unit itself is rugged, bulletproof and made of quality components. The thermostatically controlled main plugs come on when necessary and keep from needlessly wasting battery amps on the C14. The pulsing aux plugs work great for other heating strips like for eyepieces, or I even power a couple of 20" dew strips I wrap around the mount motors on the CGE in the winter. In short, an excellent, well-built product and outstanding customer service.

I purchased my Dew Buster just after I bought my telescope about four years ago. The first one I ordered got lost in the mail due to the disruption from Hurricane Katrina. I called Ron and he mailed me another one right out. Since then, my Dew Buster has performed flawlessly. Dew on my optics is one thing I do not worry about and that's saying something since I live in Georgia where the humidity at night is always high. Excellent value for the price. Ron will even customize them for you if you need something a bit different. Thanks Ron.

I've had my DewBuster for 3 years now and I am very impressed with it's quality. Prior to purchasing I looked at all the other dew removal solutions and I came back to the DewBuster. It's dependable and easy to use I highly recommend it to anyone who needs a dew removal system.

Great feedback from the moment I purchased til the time it arrived, easy to understand instructions (which you really only need to read once), set the dial and leave it for the entire session. Was so impressed that I bought another one for my second mount. Have used my DewBusters on all of my OTAs without a single issue.

I purchased the DewBuster to replace a Kendrick controller as the latter interfered with some SBIG equipment. I've never had a problem with the DewBuster, it performs as advertised. I use(d) the DewBuster on a C-14, C-11 and a few refractors.

I live in the SW of UK and we are prone to heavy dews here. I have had a Dewbuster for about 2 years now and it has been used with a variety of scopes ranging from ED80s to my current Celestron 9.25" and it has never ceased to amaze me how efficient it is in combating dew and frost. It is a simple product to set-up and use and to then just forget about, this is the sign of a well designed product. The term plug and play springs to mind. So far the Dewbuster has proved to be extremely reliable. Ron's pre and post sales support is second to none, which in this day and age of the faceless call centre is refreshing.

If you have any dew issues the DewBuster will be the best money you've ever spent, period. There's no calibration, you just power it up and forget about it. It's not a high profile/exciting piece of equipment, you don't 'see' it working, you don't have to know how it works, but you know at the end of the night, it worked flawlessly. If your not sure what to order, run it by Ron and he'll give you a hand in determining your requirements.

I have an 12 inch LX200, it has a dew shield which is OK for awhile but, if you don't ant to get shut down early then get a Dew Buster. There have been many times when I've been the last one observing when everyone else was shutdown by dew. This works so well that my tube is even dry when the rest of the scope is wet. The unit is great on power consumption and has multiple jacks for more main optics, eyepieces and finders. It comes equipped with a temp sensor which allows you to select how much power, in degrees over ambient temp, to use. If you're a serious observer or imager you need a Dew Buster. Craig Hunter SDAA

Used on my Starmaster 18. Ron was great communicating with me by email to discuss ways to power my independent secondary heater (which has its own thermostat) through the dewbuster. He added a custom outlet wired through the main switch, provided great advice, and was generally very helpful. The whole process could not have been easier, and I ended up with a custom product that is exactly what I wanted. At MASP 2008 my optics dewed over every single night. Since I installed the DB, not a drop of dew has dared come near my stuff. I made custom heating elements for my 8x50 RACI finder and eyepiece based on Ron's documentation. The elements were CHEAP to make, and they work great. As an added bonus, the eyepiece element warms my nose while I look through the scope. I have a 40Ah battery that has never dropped below about 80% charge, even after long all-nighters in cold weather. So far, I could not be happier. I have never used any of the competing products, but I can say that my DB has been an outstanding value and performer.

Here in the Pacific NW USA, humidity is a big problem. A good dew (& frost!) control is essential in order to observe more than a little while during a fair part of the year. I have had my dewbuster simultaneously keeping an 11" SCT, a 120mm refractor, and 66 & 70mm guidescopes for each quite clear on nights the finder scopes, eyepieces, tripods, my toes, etc., have all frosted up. Had a problem with the first controller I bought that was through my own ignorance, but Ron replaced it for me anyway- and advised me how to keep from goofing up again to boot! Well thought-out and built product, good price, and best of all, a real honest guy who knows what he's talking about and stands behind his product backing it up.

Hi, Living down-under in New Zealand is not the easiest when it comes to getting astro equipment at competitive prices. Ron had no problem shipping down-under at cost! Highly recommended. Even when the first dew controller failed to show up, Ron simply shipped another, no questions asked! You can't beat that for service.... The first unit eventually showed up and was returned to Ron. Used with dewnot dew straps, and I have an excellent no dew setup. Cheers Robby. :)

One of the first things that gets turned on before I start an imaging session each evening is my DewBuster. I can't state enough how much I appreciate my DewBuster and Ron's excellent response to questions and help. I do quite a bit of NEO work and I could not imagine being without this most valuable piece of equipment. Clear, Dark Skies!

I own 3 DewBuster controllers: one standard controller; one for my big dob; and one custom built for my CPC 1100/Mallincam setup where I need temperature control for the heated dew shield, a few medium power jacks for heater strips, and several 12-volt jacks for accessories. In each case they perform their tasks perfectly. The temperature control settings are easy to determine in the field and once set the controller effortlessly meets the challenge of our dew-ridden nights without burdening the battery. Ron's service will become legendary if not already. He provides the best pre- and post-sale service I've ever experienced. He's prompt and thorough with his advice, recommendations and troubleshooting. There simply can't be anyone who can claim to do it better.

THIS IS THE BEST DEW HEATER / PREVENTER ON THE MARKET! I owned competing brands before this one and always had trouble with preventing dew on my 14 without blasting it with extreme heat and causing heat plumes inside my dew shield. I highly recommend this piece of equipment - throw away your hairdryers...you won't need them anymore because this won't allow dew to form on your corrector plate. It also won't drain your battery in the field and will conserve power with its temperature sensor. Buy one today, you won't regret it!
