Nothing about the product we did not like.  As a DIY type I have installed a number of sinks over the years and was prepared to handle almost any unexpected problem.  There were none.  However, the instructions omitted one important item.  The sink comes with one hole but provisions for 3 at different locations.  I needed one of the other locations, clearly marked by a red dot.  But the instructions do not tell you how to open an additional hole.  I went to You Tube U and found a video saying it was a "supplemental instructions.  Unfortunately, the instructions in the box did not mention the supplemental.  After viewing the video, popping open the needed hole took seconds.
