This self-cleaning litter box is very simple to set up and easy to use. I like that I don't have to constantly be checking a few times a day to see when I need to clean out the litter box. It does a great job of containing odors and cleaning out the number 2 piles automatically. If we only had a single cat it would be perfect for us. But with more than two cats in our home it just wouldn't be cost effective in the long run. I wish there was a more cost effective way to refill the box inserts, like a reusable tray you could just empty and refill so it would be a better fit for our home. We ended up putting it in the guest bathroom as a back up litter box that doesn't need checked as often since they don't really go in there.
