How can I give this product any rating at this point? I have just installed it and will need at least several months to evaluate it. As far as installation, it was relatively simple. Only problem was needing to extend the vanity hole (file a deeper notch) for the drain plunger. The hole in the fixture is to far toward the back to pass through the predrilled hole in the vanity top smoothly. I also don't like that the plunger must stand at an angle when the drain is both open and closed. The design of the unit could/should be improved to eliminate this problem
