I bought this smart faucet in December of 2021 and it worked perfectly until today win the hot water valve inside the control Box stop working. Overall, I am very satisfied with the unit, however it did only last 17 months before failing. Customer service diagnosed the unit over the phone quickly and are sending me a replacement control box free of charge (minus next day shipping). I am very satisfied with their customer service and look forward to continuing to use this faucet for a few more years.
