Package (box) arrived with 2 holes in it and the small plastic covered screw filled sheet was empty of half of the contents which were scattered throughout the box. I managed to find all pieces except one screw. This is not a black stone issue but a Wayfair shipping issue.  So my rating at this point is on Wayfair and the shipping company and their lack of care with my product and the handling of it. I hope I can find a screw to match.
