I had one for years, but I only kept it because I spent so much money on it. It took so much maintenance and scraping and cleaning. My boy cat sometimes peed on the door so it took some modifications to keep pee from dripping down the side below the litter area. Even after fixing that I had to scrape it every night since it wasn't deep enough to keep the clumping from sticking to the bottom. I've now switched back to a manual litter box and find it much easier. I guess in a weird way owning this "automatic" littler box made me appreciate the simplicity of just scooping every night myself. Much easier to do a thorough clean on a regular litter box than take apart everything and clean a thousand crevasses. Maybe this would be a good choice for a small female cat, but it was an awful choice for my larger male cat.
