I've only had this faucet for a short time but it works like a dream. It's so solid compared to my previous faucet which I paid the same price for. I purchased this at a one day flash sale and I am so happy about the lifetime guarantee. I hired a professional to install it and he told me that Moen is very good about honoring their guarantees. My favorite function is the motion sensor. I can touch raw meat and eggs and wash my hands without ever touching the faucet.
