Works great, the cats are happy, and I no longer find it a disgusting chore to clean the box daily. It takes about 30 seconds and you never have to touch poop or pee again. I went (http://goo.gl/wEI6g) to the Omega Paw site where they had more specific instructions on putting this together.
If you were like me and avoided cleaning the litter box or it use to be a messy ordeal just buy this and you will solve all your future headaches. I have never been so happy to clean the litter box.
