I saw a couple of them at Repticon, they looked interesting so I looked into them. It's an unorthodox design but I think it's interesting. I like how you can knock them down and replace damaged parts. Too bad they're glass, husbandry will probably be a pain in them. I think I'll just stick to my plan of getting PVC tanks. I was wondering if anyone ever used those, I'm kinda curious to see how they'd compare to the standard glass tank design.
