This faucet has a plastic washer inside the on/off-hot/cold selector handle. It floats which means that in the 10 months we have had this faucet, it moves around and blocks the rotation motion of the handle. This necessitates removing the handle, pulling the cover off and repositioning the washer. I've had to do this numerous times and can't believe Pfizer hasn't designed a better operation. Nice appearance of the faucet but can't recommend it until it is redesigned.
