Product review (5 stars): This product worked like a hot damn
My stove and countertop are different heights and the space between them quite narrow.  This product worked like a hot damn!  I didn't even need to cut it.  I just slid the longer edge downwards and the other portion wedged in there perfectly.  It was even the right length for my standard size stove.  I'm thrilled!  No more bits and pieces of food falling down the sides to make a disgusting mess.
