So... I bought this sink last year and had a warranty return due to crack that formed along the center wall.  Support team was great to work with and I received a replacement sink within a week of sending in pictures of the problem.  Just installed the new one and I was happy to see that there were some improvements in the design!  The center wall is no longer hollow, eliminating the possibility of the same issue occurring. Additionally, the finish is much smoother on the new sink and the drain holes have been needed up.  The new sink was also exact in wall height dimensions where the old models had variance, installation was easier than I expected (had to slide under the counter).  I'm glad I stuck with this sink rather than getting one from another manufacturer!
