I had heard that all foggers don't last very long. Mine was working fine, until it didn't. It lasted about 1 year. When it worked it was great. Now I think this is just one of the expenses of having a red foot tortoise. So I am budgeting about $70 a year for this feature to Zebulun's enclosure. My Zeb started pyramiding shortly after I got her. And I knew about the importance of humidity from this forum. Achieving the humidity, that was another thing. Someone here is trying to build his own unit with a 5 gallon bucket. I'm gonna try to follow that thread. (not computer savy)
