Query: Great Product! Can't go back to regular boxes.

I started buying the littermaid back when I owned 1 cat. I have since grown to a 5 cat family and have had several units. I recently purchased the designer series. We had 2 megas and one unit did stop working after 3 years. But what do you expect with 5 cats that each can on the average use the box 5 to 10 times a day. I have read many of the reviews and can see why some folks would be disappointed. Do not expect this to be something that requires no maintanence, you do have to manage and keep up on it. It is advertised as "no more scooping" not not more cleaning! The motor is not as loud as some of the other reviewers have mentioned. The cats acclimate very quickly to it. With proper care this will last you years! I also have just seen the latest product Littermaid Elite with a steel rake and ionic air cleaner. I would have tried that one has I known it was available, looks like they made a few improvments on an already great product.
