This is the best kitchen faucet I've ever owned or used in over 50 years as a home maker. After 4 years of use, the faucet looks like new and the "MagnaTite Docking" system works as well as it did on Day 1.  I'm moving soon and plan to buy another one to replace the faucet in the new house.  I give it my highest 5 star recommendation.  Thank you Delta!
