Product review (5 stars): Should have bought these LONG ago!
MUST have if you don't like the nasty buildup of gunk from the inevitable spills. These are very high quality silicone, and seal down very nicely to both the stove and the counter top. These can be trimmed for a perfect fit, but I mine worked out nicely without trimming (thanks again to the very flexible silicone). Don't be lazy... pull the stove out & clean it right (clean the floor under there, while you're at it). Don't be "that person" who just puts these in place without first cleaning. It's NOT ok to do that. ;)
