I have had mine for almost a year now, no problems, its great sure don't miss changing the cat box! My Husband thought I was nuts to spend that much on a cat box, but if u think about how much u spend in cat litter and what your time is worth its not that much at all--by the way, he has now completely hanged his mind. I bought the one that comes with everything and put it in my laundry room which is small but works for me just had to move some things around to reach the water and drain hook up, but no big deal, now i can't see using it in the bathroom but I guess some do and it works for them. I have used all the setting and found the auto wash works the best. I have 3 cats that use it , and go inside and out all year. The only thing with mine is my cats have long hair and the hair will get wrapped around that metal rod in the hopper and the clogged drain code will light up but all i have to do is remove the hair around the rod and its fine. If u have the room i would definitively get one u won't regret it.
