Looks nice but feels very thin, cheap, & flimsy. Sounded like the plastic was going to crack when I was assembling it. Kitty was also terrified of it. We gave it several days but he avoided it like the plague (and instead went potty everywhere else around the house). Ultimately between quality concerns and the fact that kitty disapproved, we sent it back. 

Note: part of the reason we bought it was to trap litter inside. The handful of times we put the cat in the box and he came out, litter still spread everywhere. If you're buying it to reduce litter being tracked around the house, it did not remedy this issue for us in the limited time we had it.
