I've got one and it is amazing (the medium/low), I would love to get another one for when I get my second leo just don't really have the space for a second unless I can rig something up to my current set up.
We just set ours up. we have not seen Fonzi in weeks due to him in his hide all the time. So far tonight, we have seen him outside the hide and wondering around. I think he is happy with his new crib. Does a bigger tank need more heating? It is still at 80
I have a large low for my leopard geckos and they are excellent. i am going to get a med low for my AFT. Makes cleaning and spraying the tanks so much easier, and it gives them more surface area to move around considering the low ones are not the tall and nice and wide.
