I really like this system.   The rake works well and I think the litter does a pretty good job of keeping the smell down.  When I had two cats and they went in the same spot, it would soak through the paper box a bit, but now I have just one and the box holds up fine.  So easy to just put the lid on and take the whole thing out.   I also like ordering multi packs because they show up at your door with no hassle
