I bought this a week ago first used it Thanksgiving day. It work flawlessly  turning on and off with not touching the faucet, set your temperature and it’s always perfect never having to adjust. Only issue we had was on the instal, they never mentioned there was a  clear plastic film over the sensor so at  first we couldn’t get it get sensir to work until my husband happen to notice the shipping protective film on the sensor. That should be mentioned in the instructions.
