This cage is working out fairly well.  There were just a couple little issues with the cage, but neither one of them was a big enough issue to end up in returning it.  There was one little wire that had come unwelded.  It was at the top of the cage so it didn't pose that much of a problem.  The other issue is the floor plates aren't attached very well.  I think is just a poor design.  They are constantly coming unattached, especially when the gerbils run on their wheel.  It's like the plates are too loose and they don't fit right.
