We have had our Cat Genie for 18 months and it is used by both of our cats. The heater went out, my husband followed the trouble shooting instructions in the owners Manuel. We called the customer service number and in less than five minutes arrangements were made to replace the electrical unit thanks to the two year warranty! It was delivered as promised and we are back in business. We love the convenience of the genie and were very impressed with the customer service. We highly recommend this product it is worth every dime!
