We love this faucet! Didnt take long to get used to the convenience of the "touch" feature. Never have to turn the water on with messy hands, just touch faucet with your wrist or back of you hand.  
However, after being in our new house for less than a year, the touch feature stopped working out of nowhere;the solinoid had to be replaced. I spoke with Delta customer service and was sent the replacement part within a few days. Very easy fix, but and worried how long this one will last.
