Sturdy, solid, very attractive

This faucet is amazing. It looks great, feels solid and works great. The feature that allows tap in the osmosis water through the extra spout works really well. I have it installed on my island and the size and design of this faucet the “pop” that my kitchen needs. The shipping was excellent and overall I'm very happy with my purchase.
