I have to say I would add 'fragile' to the list of cons....
The one I have (which is the original cage Herbert came in, not one I purchased) has a shelf missing and the lid was broken. The clip that connects the wired bit to the bottom was also broken. Mine is held together with garden wire! :P
I think the concept is a great one, but the cage is badly made and isn't worth the money in my opinion. You'd be far better off spending your money on a Gabber Rex!
*However* it does make a great add-on cage, I have found it easy to attach to my Zoozone / Rody Cavia.
I wouldn't use this cage for a Syrian hamster either.
