Thanks for the reply 
The first time i saw it i wondered how in the world could they not have hot spots even with a rheostat. I don't understand how they make the heat rocks and why they are so different from under tank heaters. Do UTH's have hot spots at all? I wish they would just come up with a portable heater that is safe so i don't have to keep buying more and more heating pads.
Anyways, thanks again for letting me know
