We purchased this faucet in December and just love it.  We recommend it to everyone. The motion sensor works exceptionally well, theres no delay and it always turns on or off as expected (unlike public restrooms where you can never get the water to turn on)  The features are great, such as the spray and auto shut off when returning the spray nosel to the faucet base.  Keeps faucet clean, and its great when washing meats or anything that you would not want to touch the faucet while cleaning.
The faucet can be challenging for guests using your kitchen sink, so you will need to explain how the faucet works when people are not familiar with sensor faucets.  Would never go back to a manual faucet.
