I bought this litter box about 2 years ago, after less than 1 year of use the motor died. I called customer service and got a complete new replacement unit sent to me at no charge. 1 year after using the new unit the motor died again!!I called customer service again and was told the replacement unit they sent DOES NOT have a warranty and I would have to pay a $65 service fee for another replacement unit that would also NOT have a warranty.I was quite surprised that a brand new unit sent from the manufacturer would not have the standard warranty. This indicates a complete lack of trust in their product and extremely poor customer service.Be aware that this unit will only give you 1-2 years of service!!
