Dr Infrared Heater DR 122 Bedbug Heater with Thermometer and Timer Black Big

Takes a little bit of time but it kills them real good, it brings me comfort to know they burn to a crisp in there. Fairly easy to set up and use, and when sealed up properly it keeps its heat level nice. And it's a heck of a lot cheaper and easier to use than an exterminator

So, the thing works well. The frame is cleverly designed with springy pins to hold it together. The nylon canvas bag that surrounds it is of good material and well made. It gets up to temperature and stays hot and works for what it's intended. There are a few things that people should know about it however. There is no thermostat on the heater. It's just a heater with a switch. The thermometer-timer is a separate thing and does not control the heater. You have to keep an eye on the time and temperature and turn the heater off yourself. Not a big deal but something to be aware of. You'll need to stay near it and listen for the (faint) beeping of the timer then turn it off. They say that it should be at least 49°c to kill the bugs. This can go up to 59° and 60°c. This might be too high for some objects. The ambient temperature of the room you put it in has an influence on the internal temperature. The heater switch has four positions. OFF, FAN, HI and HI. The manual says nothing about what the difference is between the two HI positions. In practise they seem to be the same. There is no mention of the orientation of the vertical supports in the manual. It's important for the racks though so that should be mentioned. The racks are well designed but there is a limit to the weight they can hold without sagging. The vertical zipper teeth were separating on the second day. This is likely because the zipper slider is a bit too cheap. (They should use a better quality of zipper slider.) Squeezing the slider with pliers works for awhile. The cooker doesn't get hot enough with the front vertical zipper not closed.

Easy to set up and use. Loses a star because the shelving that comes with it is weak. I used both shelves as one and placed a shoe rack inside and that has been good for me. No other issues so far.

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.

This product was defective. It turns on and then shuts down after 30 seconds. Completely dead on arrival out of the box. There is no automatic temperature control as suggested. No timer. This is not a good product and now it is taking space and costed me money. Don't buy this. I have tried to return this but unable.
