Trouble from the start.  First the faucet, drain and overflow holes do not line up. Not a huge deal.  Second the plumbers really struggled to not get the drain to not leak.  They believed it was due to improper casting. Then overflow drain leads to a hole in the bottom of the sink instead of back into drain as it should. Lastly began leaking again from another hole at the bottom after day 2. The sink was made this way so I would have had no idea about this upon initial inspection. Still spent almost $400 on this.  Super disappointed because Swiss Madison requires a licensed plumber to install the sink in order to honor warranty (which I had done) but will not pay for that service on a replacement so now I will spend more on plumber installation than the cost of the sink.
