Awesome faucet. It arrived within 2 weeks from order. Came packaged well. It was easy to install, instructions were clear and precise. The motion is detected by a box hooked up under the sink that is ran on 4 AA batteries. Time will tell how long the batteries will last. One complaint, I did not realize that it did not have a single hole install plate included. It is optional. It comes with the 3 hole plate but we wanted to single hole install. We didn't realize that until after we had already removed (forcefully) our other faucet so we had to go with no plate install. The neat thing is in addition to the motion sensor turning on and off the faucet, when you pull out the spray head it turns on and when you put it back it turns off. Overall it is a great faucet. Super happy with my purchase.
