I bought this is January for my builder to install in our new house.  After his licensed plumber installed it, the sensors would not work and the water kept cycling on and off regardless of the handle position.  Took three days to get someone from Moen on the phone but rapidly diagnosed the problem as a control box failure.  They are sending a replacement via USPS but they are out of stock.  More are expected in 10 calendar days.  Not what I expected from Moen.
