I live in upper Michigan where I use my furnace for heating a lot more than I do cooling. Have people had problems with these melting?

I don't know since I didn't even use it for cooling. As I mentioned in my review this air deflector is for floor registers only and it won't fit ceiling or wall registers. I seriously doubt though that it would melt. It looks durable to me.

Haven't had any issues using these for heating or cooling and I have 3 of them on the main level of my house. You should be fine using these on your vents in the winter unless they get really hot. If your vents get hot enough to melt plastic, you have other problems. :)

We used ours through the entire winter and summer with no issues in southern Ohio. They did exactly what they were supposed to.

I had to send it back because it is very small. Also I would not use it for a heating vent, I was gonna use it for a air condition vent.

I haven't had any issue with heat with mine. But I wouldn't use a real high heat with even heat protected

No, they haven't for me. I do not use high heat, though. Medium high is best.

No problems with mine. To save money, I even just went to a hardware store and got a furnace filter and cut it to size for about $7.50. Saved about $20.00

I too haven't had any issues. There are heat settings that you can adjust. If it doesn't heat up, you may have a defective unit.

No. Max temp of this furnace is around 900 degrees F. Gold melts at 1974 degrees F. Silver melt 1761 degrees F. And the bad news... if you have lead around 1974, it would be reaching a deadly boiling and vapor stage. The furnace is made for lead... not gold, not silver.

I did not have this experience. I would not use them. Could be faulty heating coils. I wouldn't risk using them.

I use these all the time and I don't have any problems with them. It might be your burn speed is set to high.

I have had no issues with heat. This device is perfect for regulating the speed of an inline fan I use to pump heat downstairs in the winter, and cool basement air upstairs in the summer.

Has not been a problem with mine. I would suggest that the metal heating(expanding) and contracting((cooling) with these cycles could be the reason. Still works great for us after several years of consistent use.

mines were melted as well. I just pulled a small amount off and still eat it. Some you can pull a part with no problem. I am thinking, keep in refrig during the summer time.

Recommendation is to use med heat ... Pot is not big enough for high heat ... I've been using it on gas for a while now and no problems with melting as long as you keep the flame to the bottom part of the pot.

Never have had a problem. Live in a northern state and have survived 6 winters without issue.

After a year I had mine melt into the dash one day in Seattle. I have a review with pictures in that section. It has seen hotter weather but something about today (68 degrees measured in the shade) and it decided to melt.

I have had no problems, but i'm sure if the stove is on high and you boil all the water away melting could occur.

We do not but with our packaging technique we have not had any issues with melting, even on hot days. It is best, however, to wait to order if the temperature is extremely high.
