I purchased this unit over twenty years ago. It was an easy install with no problem. Over the years it needed the replacement of the main shut off valve system and the faucet because of pitting. After all these years I feel fortunate I didn't have to buy a whole new one because they sent each part as I needed it at NO CHARGE which I am grateful. It has gone thorough two kitchen remodels and is still a great unit. I am looking forward to another twenty years of not having to buy another Kitchen faucet. All it took was a phone call and they mailed it out with no hesitation. Thank you.
