Query: Good in theory - awful in my home

My mother in law bought us one of these. Honestly, Im using it because she would ask where it was if I went back to my sifting pan. My issues with this include: The motor is not strong enough to move the litter (its plenty loud, though); the collection trays are weak and break all the time; its IMPOSSIBLE to clean, unless you want to spend all day on it; it requires the most expensive litter on the market; The cover for the collection trays doesnt fit properly, meaning the smell can get out ... I have other issues with it, and I dont think it is particularly well made - my parents in law got it from a late night infomercial, so that should ring alarm bells right there.
