I tried Addison single handle pull down kitchen faucet with touch20 tech for free.  We switched our faucet in the kitchen sink with this.  It was a big job installing and switching the wires and pipes that goes with it. It took us longer to hook it up. But it made my sink looking high tech and cool. So far, it has been working and running great. No complaints yet. We will see how this goes because this is a tap, hands free faucet. Hopefully, this will stay like this. Kids would be curious to tap and play. Crossing my fingers.
