Give me a break, I have three cats. This thing is a godsend. I can't believe people complaining about it breaking down in a few months or it being overloaded. Read the manual is all I can say. I have bought about four of these units. I started buying them when they first came out and they cost about $200 plus shipping. They have vastly improved the durability and features, and the cost has dropped dramatically. If you adhere to the rules of not over filling it with litter and checking the receptacle box daily you will find it works very well.
