So far so good! the contractor installed the sink yesterday.Haven't used it yet. It's a beautiful sink.  Very heavy though, took a while to install. The contractor couldn't find the template for the sink cut out at first. He was looking at the paperwork that came with the sink. It's actually a piece of cardboard. I was also a little concerned about the slope of the sink but you can't even see it. Love this sink! Can't wait to start using it.
