We bought this faucet and 2 matching soap dispensers when we got a new sink.  There have been nothing but problems with the faucet and 1 of the soap dispensers.   2 sets of replacement parts for the soap dispenser and it kind of works, but still doesn't dispense as well as the other. 
The faucet has a new solenoid and battery pack,  but still doesn't work well.   Sometimes shuts off on its own,  sometimes turns on by itself,  sometimes won't turn on at all.   We have jumped through Delta's hoops about laying the battery pack flat (must make batteries work better than being upright)  to adjusting all the wires.  They finally advised us how to turn it into a manual only faucet.  So much for spending the extra money on touch faucets. 
Not worth the money.
