The good points to this cage are that it looks neat, that you can see what your pet is doing, even when they burrow, the wheel size is ok for small rodents and it's easy to clean. The base comes apart, so we take off the front which makes catching our gerbils after they've had a run around my son's room much easier. The not so good points are that it could be bigger. I'd have paid more for a larger version. There are no air holes for the base, so they have to keep some of the upper floor surface as wire, which isn't good for tiny paws. I don't really like the tube, a ramp or angled tube would be better. One of my gerbils won't use it which makes this cage a bit pointless. I'm therefore going to have to remove the tube and add a ladder. All in all, it's ok but not the best design really.
