Product review (5 stars): can easily be moved for more thorough wiping when needed
They are exactly what was described and I wanted. Not sure why some reviews called them flimsy.  It's a sheet of silicone pressed out to meet specifications for gaps between the countertop and stove.  I wouldn't want anything thicker; since, it would rise too high off the counter. They are unobtrusive and lay flat to seal everything out.  The silicone grips the surfaces of the stove and countertop; yet, can easily be moved for more thorough wiping when needed.
