### ⭐⭐⭐⭐⭐ 







  
  
    Spectacular! Perfect Ball Python Floor Temp!
  

*by M***A on Reviewed in the United States on July 4, 2017*

I purchased this UTH for my ball python's new terrarium, and it works well! After monitoring it for 2 weeks (inside temps stay around 76-78*F), I've never had the floor temps get above 90* F (I placed my probe against the glass under about 1/2"-3/4" of coconut fiber bedding). It does a phenomenal job of keeping the floor temps in the ideal range, without getting too hot or too cold.  Best of all, I can remove and replace it as needed, unlike many commercially-available UTH mats that need to stay put once applied. Quality product!

### ⭐⭐⭐⭐⭐ 







  
  
    Works great!
  

*by K***Y on Reviewed in the United States on November 10, 2018*

Works great for my 72 gallon hermit crab tank. My temperature has stayed nice and even around 81 degrees. I did insulate this with foil-covered cardboard taped over it, so that does help keep the heat in. But it seems to be a good heater. For hermit crabs, by the way, you put it on the back, not under the tank.
