Product review (5 stars): Place them with the wide side facing toward the counter!
I just updated my review from 3 stars to 5 stars.  I have never owned such a product, but we were getting quite a bit of food debris in-between the cabinets and the stove.  I ordered these, but apparently put them on facing the wrong direction.  When my husband used our wide gas burner, the flame reached the strip and melted part of it.  At that time, I realized we needed to face the narrow side toward the burners and the wide side toward the counter tops.  Within 24 hours of my first review, I was sent a new set of seals by the retailer.  Since we started using them, I have turned the oven to 500 degrees and there has been no change in the silicone.  We have also had no problems with the flames melting the narrower edges.  I also like how the silicone is soft and flexible.  I can easily run them under the water and wash them with a bit of dish soap to remove the grease splatters.  They were a bit long for our counter top but they cut very easily with kitchen scissors.  I have since recommended them to my mother as hers are not silicone and they slide all over her counter top.  These remain "stuck" because of the silicone. I highly recommend these!
