So I've done the search for this on the forum and it returned 3 posts from folks asking the same question as myself; does anyone have any experience, good or bad, using the Zoo Med Hygrotherm?
I have one that I have had for two years. And it's been used constantly 24/7 ever since I took it out of the package, Works great for me. I'd recommend it.
I was looking at these if any of them help, I don't know how much the Zoomed one is but if its anything like every other reptile supply its a little more expensive lol
