I have purchased 4 of his cages and I must say that they are awesome. Easy to clean (seamed sealed rounded edges) and smooth (no rough spots for stuff to stick in. The design is great. I just moved from Portland Oregon to SC and the humidity stayed right at 55% in both locations even though the two states have vastly different humidity levels. Like another person said, light and the heat is built in...use a rheostat or thermostat (preferred). I got a light in one but find that I don't really ever use it, so unless you just have to have it forgo that option. Great construction!!! I will buy more if I get more BP's.
