This unit makes being a cat owner a piece of cake. Great for those who hate scooping the litter box or the lingering smells that comes with it. Another benefit, if the unit is still under warranty and there is an issue with it, the customer service reps are wonderful! They are knowledgeable for troubleshooting over the phone and if that does not help, parts arrive the very NEXT DAY! Couldn't ask for anything more.
