Works as it should.

The drain fit under my vessel sink that had drawers right below the sink, that is the reason why we got it. We had to buy another part for thus drain from a different supplier. This drain was made with overflow holes. The part we had to buy was solid without overflow holes. Kohler needs to make one without overflow holes for vessel stone sinks that do not have overflow option. Otherwise Kohler the drain works fine with 3rd party part added.
