yes i like the herpstat 2 which is the one i will be ordering. im just worried that if the ambient air temps are not high enough and i have to use a radiant heat panel then i will need to get another one to measure both cages unless i buy a herpstat 4 right from the get go and if i dont need the r.h.p then i can control 4 cages when i get them. hmm decisions decisions.
