I have 2 boxes the classic and the other is very similar with a scoop counter, that I don't see it on the website anymore. Both boxes function as described. I was surprised at how well the crystal litter controls odor. The paper tray actually holds everything and is convenient. It doesn't leak. The litter doesn't NOT last 30 days. We still have 3 boxes for 2 cats and it lasts between 30-40 USES not days. I have 1 cat that didn't like the blue litter so I got the unscented trays and the other cat didn't like that. So I bought the plastic reusable tray and found another brand crystal litter that they would both use. If you go that route I recommend the stainless tray instead because the plastic really gets stinky no matter how much washing I do. Overall this is a great budget friendly automated box for those of us with cats that only like open boxes.

We have 2 cats- an older very tidy female and a large, rescue male "kitten" who is too aggressive to share the same space with her at night. He keeps both litter boxes messy and smelly. I'm very pleased with my first crystal litter box which drastically reduced the smell and my cleaning work, so I'm getting a second one to be delivered tomorrow!

Overall best ! Even better than the more expensive one we had

This is the worst product I have ever purchased. There is more cleaning with this product then there is with a regular cat box. I'm never buying a so called self cleaning litter box again.
