works but now I can’t use it

I had mine for a little under a year and it was great but it won’t stick to my tank anymore. I tried re applying it but it falls off in an hour.

Heat Mat Fail

This worked as expected the first week but now it's not putting out any heat at all. I would not recommend.

This heat pad works well for heating and is very flat against glass, but once it is placed, you cannot remove it whatsoever. It is very difficult and every part you get off, leave all of the adhesive on the glass. If you want it off you will need a new tank unless you are ok with a giant splotchy spot.

Work great for smaller reptiles & tanks!

I use these for my scorpion, leopard gecko and my young corn snake. They are amazing! They don’t get too hot and they definitely provide the necessary warmth. They’re super easy to use and so far, none have burned out! I definitely recommend them!

good heat!

I bought this heat mat for my leopard gecko after her old one died. Much bigger than expected but a good thing! Stays warm and is consistent especially with it hooked up to a thermostat

Works great, reasonable price

We have a 20 gallon tank for our leopard gecko, and this mat makes it toasty warm even in the cold winter months. I had to move it away from her water dish so it wouldn't evaporate too quickly, and I had to move her sleeping enclosure because it was so hot she wouldn't go inside! It's a great supplement to the heat lamp on top, which is fine by itself in summer but nowhere near enough to keep the tank warm in winter.
