Not completely satisfied with this product. I enjoy not having to clean the litter box daily, but I still have to clean out number two once a week or it will mold and smell awful. The litter only lasts between 20-30 cycles (not days!) before the smell of urine permeates the room. I'm having to change litter about every 2 1/2 weeks and that is getting expensive. The metal grate gets stuck half way when scooping number two.  I was hoping for less work and cost but this product didn't deliver.
