Overall it’s an okay product however now I only use it for when I’m going away. For that it’s good because it removes the feaces into the compartment. However, it’s very expensive to keep it up with the refills. Also the box is awkward to dispose off and takes a lot of space in the bin. It’s difficult for the cat to burry their business and unfortunately it smells so bad until the timer is activated and it’s taken away. Cat also likes to play with the moving metal. Hard to clean, poo gets stuck.
