Do you have your heat mats plugged into a power strip, and then the thermostat? I was wondering if that works well, I'm thinking of doing it myself when I get my next snake in, at least until I get an actual rack with heat tape and a better thermostat. I currently have 2 of the one you're using, one for each snake I have so far. I was hoping I'd be able to put 2 on one and then use the other for my newest snake I'm getting soon, since I have a different sized heat mat for her since she's smaller.
