The installation was easy, I did it myself. All the necessary components came with it, including batteries. I did install the optional ac power adapter, which saves the batteries in case of a power outage. The pull out sprayer with magnetic docking works very smoothly. The switch on the sprayer head to change from steady stream to spraying is a nice feature. LED temperature sensor light in the base is a great feature, too. allows you to see the water temperature without placing your hand in the water. The absolute best feature is the Touch2O technology. At first I didn't think we would use it that much, but I was wrong, we use it all the time. It is so handy. We have only had the faucet for a month, but so far it is working flawlessly and it adds the finishing touch to our kitchen.
