Product review (5 stars): Looks great!
When I got a new gas stove to replace a drop-in, there was an ugly gap between the stove and countertop.  My new stove is stainless, but the top is black, so the black extender is virtually unnoticeable! On occasion, it is necessary to remove the extender to clean, but that is no trouble at all. I am extremely pleased with my purchase.
