I had seen this on TV I think and thought that it was fake, so I went on the web site and read several reviews before buying it for my cat. I put it in the laundry room where her other litter box was at and hooked it up myself. The only problem I had was that I didn't tighten it at first with the pliers, my fault. After I turned it on and was running the cycles through to make sure that it worked properly I picked up my cat and took her in to the laundry room with me. She watched it for a bit then I put her down and started giving her some treats near it so that she would get used to it. Well that was weeks ago and no problems at all. She started using the new litter box that night. I have told several of my friends about it at work and they are considering getting one also. Love it.
