I got a total of 5 cages. I use RHPs in all the cages instead of CHEs, but the result is the same. Overhead heat. There is one that also has an uth. I agree about buying a uth on Amazon, a few years back over about an 8 month period, I bought 2 zoomed uth. The 1st did not work at all out of the package. The 2nd would only get to about 82 degrees on the pad.
