I have one! I spoil my cats. Yes, it is convenient but you still have to check it at least once a day, just to make sure it doesn't jam. The motor isn't all that strong so if the cat decides he wants to shovel all the litter onto one side of the box then it'll jam. I have 2 cats, takes 2 days before the box gets full and I have to empty it. The cats still get litter all over the place, and be prepared for a lot of litter spillage around the box (just the litter, not their crap or anything). But overall I like this a lot more than a normal box. Now I can actually leave my cats in the apt for the weekend and not worry about accidents.
