Ok, I was pretty skeptical about this self cleaning litter box from PetSafe. The setup was a breeze. Just place the top over the box of litter making sure the magnets line up on the door, plug in and you are ready to go.  My cat took to it immediately. Best thing....no odors! With one cat you can get about a month out of it before needing to replace the litter. When it is time to replace it, you just lift the top off and the small box of litter has a lid it is sitting in. Take that off, cover the top with it and dispose of the whole thing. Easy peasy! Wish I would have tried this sooner! Couldn’t be happier at this point.
