Product review (5 stars): Best Stove Gap Seal
Very high quality product.  I was expecting a hard, in flexible, plastic-like, gap cover.  To my surprise, this product is made of flexible silicone that creates a suction like attachment to the stove and to the counter.  It installs easily just by pressing it down tightly into the gap.  The material appears to be long lasting and easy to clean.  I am very happy with this purchase.
