They have sold about 3 million of the LitterMaids so far and I think that it is a very good product. Quite often buyers will throw out a unit and buy another one when the problem could be fixed in less than a minute. The LitterMaid help desk is no help! And, of course, they want you to purchase new one. To find out how to fix your LitterMaid, purchase the LitterMaid Repair Manual that can be found at http://www.catboxking.com
