The faucet is well built and looks better than the Delta faucets that we looked at. It has an"O" ring at the bottom mounting area to ensure an solid and dry mounting for a single hole sink. The Deltas did'nt have one. BUT I wish it had a magnet held sprayer tip instead of the plastic retainer that you have to push the sprayer into. It holds ok, you need to line it up to insert it. The wife likes it, it was her birthday gift, and she will think of it each time she goes to sink.
