After installation, there were just a few quirks with the consistency of this faucet.  Sometimes it would turn on by itself and other times I could not turn it on or off using the touch feature.  But after it settled in for some time, it has been functioning really well.  The touch faucet has been an amazing buy and it's definitely a conversation piece.  My wife and I really didn't think we needed a touch faucet until we started using one...a must buy.
