So far so good, we've only had it for a couple weeks. It is VERY quiet which is wonderful since the last automatic litter box was so loud and always banging and just a nightmare. I like that the top 2 pieces can be removed for deep cleaning as well as the drawer. This wasn't an option with the last box we had and that thing became a nightmare. The app is very easy to set up and use as well! Will update this review if anything changes, but for right now we are extremely happy with this litter box and for the price and so are our kitties! We have 2 kitties and empty the drawer every 3 days to maintain cleanliness.
