Product review (5 stars): Super simple design but one of the best inventions ever!!!
My wife seems to spill food whenever she cooks and even though the gap between the counter and the range top is only about an 1/8-1/4 of an inch, food always seems to fall right in the crack. These Kohzie gap covers do a nice job in preventing spills from falling through the cracks. They are super easy to clean as they are made of silicone, you can decide where you want to cover more of ( range or counter) since the divider that goes between the gap is offset more to one side and they can easily be trimmed with a pair of scissors to perfectly fit the length.

My range top is the glass type so I imagine some heat does get to the gap covers but so far after a week of daily use, they still look and feel brand new. Just don't let it directly touch the burners which I haven't done yet and remember you can turn the gap covers around so that the wide side goes over the counter and less material goes on the range if your heating element is close to the edge.
