I have one and like it. Instead of sifting and dealing with cleaning on a regular basis, I basically just have to empty a bag and top up the litter once a week or so and spray the globe down about once every other month. The only negative thing about the new model is sometimes if the cat is pointed in a specific way, urine sent towards the front will drip through the system and wind up below the collection tray. My cat also sometimes stands in such a way that he'll poop on a slope causing it to roll towards his back paws and get in on his paws or tail due to the lack of room. Ymmv. It's still worth having to me.
