From everyone, & including myself, Herpstat is the way to go for sure. I actually bought 2 Herpstat's..One to control my UTH on my warm side for a basking spot under the warmside hide. And now i just hooked up another UTH under the coolside hide which is also ran by a Herpstat. The reason i got 2 is if i woulda bought the Herpstat Pro & it would happen to fail (which is VERY unlikely) it wouldnt screw over both my UTH's, plus im runing each at different temps. I wanted to bump my temps up on the coolside a bit, so thats why i got a UTH+Herpstat combo for that side. But yeah man, i ordered & it only took 2 days. And the customer service is awesome! Dion is a very cool dude. And Herpstat's are very accurit( like in 10th's of a degree). You get what you pay for, and imo its the best! With those, my temps are dead on and i dont have to worry one bit about "readjusting" or anything of that sort. And my little buddy has no complaints.
