While this is a good looking cage, Im not really impressed with the construction. It arrived with bent bars all over and the bottom grill doesnt lay flat. Im going to have to use zip ties all over it to keep certain parts secured properly. It doesnt actually attach to the roller base and they literally welded washers to the frame in places to keep the cage from sliding off the roller base. I do like that it rolls smoothly and isnt super heavy but im not sure how long it will last.
