This is an incredible product. My first cat genie arrived 8 years ago. My son suggested I buy one since my back was in bad shape. 8 years later, my back has been fixed, but I love love love the genie. My 60 model finally wore out after 8 years, and since it's so old they don't have the parts for it. So I bought the 120. Can't believe how awesome it is. My 2nd cat refused to use the first genie. After 2 weeks he finally decided the new 120 was a good thing. It's always clean. Finally I was able to throw away the nasty box I had to scoop for him. He earned his cap and gown and I am a happy cat owner. Every cat owner should have one. I also love the customer service. Quick, knowledgable, helpful and friendly. I give Cat Genie a 10 star recommendation.
