Very pleased. I have ownd a Littermaid for the past 8 years and have found this product to be a great time saver. My cat never has a dirty litter box and I use a great deal less litter. This is my second littermaid in 8 years. the first one was no longer auto cleaning and required a manual reset to get the cleaner to run. I beleive the sensor was bad. I was tired of having to remember to reset it so I bought another one. Definately worth the money!
