Product review (5 stars): Excellent choice
I had been looking for one of these for ages, and finally found it!  These seam protectors are silicone, so very flexible and able to withstand high heat, so no worries of starting a fire when they are within a few inches of a burner or flame.  Incredibly easy to use, wide enough to cover the typical gap between the stove and counter, and super easy to clean.  Also, I found them very easy to trim, as they were just a tad long for my stove.

They are very flexible, and when placed, they actually molded to the space to make a smooth surface.  These are a great product, especially for the price.

Note:  I did receive a discount on this product in order to test and review for the Amazon community.
