I upgraded faucet through builder with new construction home. Touchless faucet is so easy to use. Just a wave of the hand turns faucet on and off. So convenient when hands are full or wet. Only complaint is in 6 months, I've already changed my 6-D  batteries 3 times. I've been using alkaline batteries. Wondering if lithium batteries will make a difference. I live by myself and have only had guests use faucet during holiday stays. Love convenience of faucet but concerned about having to change batteries so often.
