Dr Infrared Heater Upgraded Version 2-Tier 18 Cubic feet Portable Bedbug Heater with Thermometer and Timer, Black, Big (DR-122)

It is large - which was what was needed when battling a bed bug crisis. And the best price around for this specific, seemingly rare and odd requirement. I appreciated having the racks to set several items in the space. It may take a little effort to set up, but no big deal. The heating blower quit on me a couple of times, but given 15-30 minutes to cool down did the trick before turning on again (I used the heck out of this thing). DO NOT put photos in this unit - I made the mistake of putting a locket in there and the images faded. Now I just need to figure out how and where I want to store this to hopefully never need again.

Some people who moved me gave me bed bugs so I use this along with getting rid of my mattress couch and chair. But this did a wonderful job. So I got rid of them. The heat output was exceptional and it wasn't too hard to put together

Large capacity makes fast work of baggage and clothing.A quick wipe down of the bottom after running the first suitcase and contents through showed 3 dead bedbugs and some other little bugs I couldn't identify, which was the kind of thing that keeps me scratching at nonexistent critters.I bought it as a mental health insurance type item. I don't want to think that expensive, well known hotel chains might have bedbugs, but didn't want to risk it. They really are everywhere and almost impossible to get rid of. The cost was completely recouped in the first use, not to mention the peace of mind that comes with knowing I'm killing the evil little monsters before they can make a permanent home here. Even if you only take a single yearly vacation, buy this, and use it. Maybe if enough people do, the bedbug population will not only stop growing, but hopefully decline to the point that technology can catch up and eliminate the threat.My only complaints would be the complete lack of directors for the case itself. The directions only handle the frame. I had to figure out the case by looking at the picture and moving it around until I finally got it right. I'm also concerned about the center zipper. With the connection being at the top, instead of at the bottom, the constant downward pressure makes it more likely to fail. It is more logical to reverse that but it can't be done by the purchaser, it's a design flaw that has to be corrected on the manufacturer's end so I'll keep my fingers crossed that it holds for a long time as we will be using this on a weekly basis.

After a bed bug infestation cost us several thousand dollars in exterminator fees, I went looking for a device to use when I got home from my many business travels (last year, pre-CoViD19.)This was a nicely priced item with good capacity, so I bought it and used it several times (last year.) As far as funciton, it does what it says it does and is easy to use, but requires you to set aside an hour or more of time "babysitting it" if you have any items that could be damaged by extreme heat. The challenge is that the thermometer they include does NOT automatically control the heater. So you have to turn it on, wait for the temp to hit the target temp you set (there are instructions on how to set an alert on the included thermomoeter when this happens) and then keep switching it on and off to keep it above the desired killing range. This isn't the end of the world, but if they offered an upgraded model with an auto- control setting that was close in price, I'd pick it over this one. As it stands, it works fine, just make sure you keep an eye on the temp while running it to keep it in range. I also noticed a lot of people complaining about the heater shutting down or dying due to overheating, so make sure the port the heater attaches into is clear and not obstructed to minimize the risk of this happening to you.The person who said the frame is weak is "sort of" right: the shelves fold in the middle for storage and when in use they do sag a little, but I have put a LOT of weight on mine and only been casual (ie not super-careful, but not throwing it in basketball-style either) about setting my full size and filled to the brim travel suitcase in it without damaging the rack.

The hot box itself is pretty decently built, although it could stand to be a bit larger... The shelf is a joke, stack things up in a way to support the thing, it's pretty damn flimsy and I thought it was gonna snap. The heater, leave the knob on the ON position because the hot glue from the LED that they put there will glue the knob to whatever position it was in when the glue cools, I recommend just unplugging the thing. Also, what idiot puts the switch and the indicator light on the INSIDE of the unit, and on top of that, puts hot glue on something that gets over 120F? The thermal switch failed on me, but I was able to fix the problem and it is working well so far afterwards...

I was waiting for a review on the upgraded version to see if all of the problems on this infrared heater were corrected. No one really gave a current review on the upgraded changes so I went out on a limb and purchased one, June of 2018. I was so happy to see that the upgraded version has in fact corrected all of the problems that people discovered. First of all, the knob to the heater is no longer a knob but a red off, on switch with a light built into it. The switch is on the back of the heater where it is easily accessed. I'm not sure what the hot glue issue was that people were referring to but there is no hot glue anywhere on the heater. The rack is very strong and sturdy and not flimsy so I think that was fixed too. Also, it is white and not silver. Also the frame was very easy to put together. It took my 12 year old, 10 minutes to put together. Also. The allowance on the case is perfect. There were no fit issues at all in placing and zipping the case around the frame. The quality is exceptional all around especially for the price. Today I will heat treat some items and update my review on the performance of the heater as well but overall, I'm very impressed with the quality that I see. I'm just a regular Amazon consumer so I think it was important to get my point of view out there because I myself was looking for a review like mine about this item.
