Product design note
Poor finish, stains easily.  Poor design, the bottom edge it sits on is about 1/2" and flat.  This edge fits on and is supposed to sit on the elevated, curved rim around the stovetop, but it slides off easily (becomes un-level) even if lightly bumped or you are moving items on the surface.  Better if bottom edges are wider and/or router curved so it does not slide off.  Good luck with their customer service.
