We bought this litter because we have 2 cats and litter is often tedious chore. With this, it's going so much faster! A lever once, and it's done! I think it's great! Well, the system is not infallible (my cat urinated on the grid once, so it was a bit stuffy and it flowed directly into the waste bin), but I remain very satisfied. For now, no smell, emptying the tank once a week. We begin to feel a little odor when cats go through the hatch, I think it will still clean the litter from top to bottom once a month to ensure that it does not feel too. Positive: it greatly simplifies life! Faster and less restrictive! Negative: litter take up much room, and the entrance is a little high, little kitten was struggling to get in early.
