100% worth the money. I got the biggest one they have available as I have multiple cats. This is fantastic!! I only have to empty the tray about once a week. And all you do is pull the bag out and put a new bag in. I don't even have to look to see if the drawer is full. There is a light that tells you when it's full. So easy!! No smell!!! Truly a life savor. No more scooping everyday.
