The drain seems to be a good product, but one out of two leaks when the center plunger is pushed down,  I contacted the manufacturer, Kingston Brass, about the problem and he said I had to return the drain to where I bought it.  Well that would require taking it out and leaving the drain wide open.  I asked him why he couldn't send me a new top button to replace the one on the drain, since it had a year's warranty.  I have not heard anything from him again.  So from what has happened, I guess he just blew me off and will not do anything to try to make the drain work properly.  I would not recommend buying this item since the manufacturer is not going to help with any problems!!  So if you want a drain that looks nice but may not work correctly or within a year or two it quits working, then this is what you want as long as you realize you will have to replace it with another drain at that time.
