Bought this faucet about 8 years ago when we built our new home. After 5 or 6 years, the base of the faucet had corrosion on it to the point it was crumbling and the sprayer quit working. After contacting the company and providing a picture, this product was replaced. We have had the new one for a couple of years now and it has been great. The single knob is so easy to turn on and off even with dirty or full hands.
