Yes both mats are identical. Both tanks have a thermometer/hygrometer fixed to the tank, and I have an infrared temp gun as well. I may just splurge on getting both thermostats from the pet store, they had two available and I don't get paid til Friday. No need to risk anything.

I have Hydrofarms right now, but I'm gonna pick up the Zilla ones because I hear generally good reviews for running one-to-one power, and they're specialized for reptile UTHs.
