I've owned 8 of these cages. The down side is that the darn wheels break off over time, and they don't make replacement casters for them. These are push on casters; not the screw in kind. Two of my cages are now on furniture coasters because all their wheels have snapped off.
I've since replaced 4 of them with A&E and Hendrix Preview cages.
What I do like about these cages is that they are very roomy for the low price.
