Product review (1 stars): IMCG Silver Gas Range Protectors are worthless
I was surprised at how thin they were when they arrived - they appeared flimsy and proved to be just that.
If any droplet of oil spatters on them when they are heated it will cook through the material and create permanent unsightly blotches.  They slip out of place easily if the burner is bumped and get too close to the flame and singe. A total waste of money.
