Love the deep “D” shape.

Love the deep “D” shape. It fits very nicely in a corner cabinet. Lots of usable space behind the sink. Two drawbacks when compared to stainless: Like all granite surfaces, china and glass breaks easily. It does not drain/washdown as well as stainless, thus you use more water. I am not sure if it the angle of the bottom or the roughness of the surface?
