Product review (5 stars): Well worth the price.
Solves a problem I didn't know I had until I moved out my old range to replace it with my current range.  It was a mess between the range and cabinets due to spilled food & boil overs but we couldn't see the problem.  These extenders are magnetic on one side and stick tightly to the range. They cover the opening between the range and the cabinets completely; side to side & front to back.
