Works great! Has a very thin, flat profile that is perfect for placing under a plastic tub, way better that the reptile terrarium heaters I was using. Recommend you place a towel between the mat and the tub, it will provide more insulation and more even heat.

Arrived faster than expected and has made a huge difference in my inoculating. Will definitely do business with these folks again

Turn in on leave it be, does what it’s supposed to do. Takes out guess work and with my busy life i don’t have to think about it

This heat mat is great for growing mushrooms. The heat is very soft and does not dry out my bulk grows like regular ones do. The heat is also very even. I am part of many online forums and people always tell me to heat the room and not the tub, well thats hard to do for some and can be very expensive. I have used this heat mat for almost a year now and the only reason I give it 4/5 stars is because I wish there was numbers to tell you what level of heat you were at, its nice because you can make tiny adjustments but if you accidentally turn the knob you have to start over. I guess not a big deal but I give it 90/100 in terms of my review. Oh and it only uses 27 watts of power which is like nothing! Less than a light bulb to run!!

Performs as well or better than advertised. Great price, and uses very little energy.
