Yeah, I've unplugged the UTH so I can check it out sometime, I may just need to replace it, honestly. It is old, I've had it for two years, it came with my Bearded Dragon's first cage. I got that cage from a teacher who had a son that kept herps while in high school (he's past college and everything), so I can only imagine how old it is exactly. I think it's a Zoo Med but don't hold me to it I'll have to check.
