Product review (5 stars): Protects my stove from grease.  What more can I ask.
I was bit skeptical when I saw the dodgy packaging (i.e. saran wrap) but rest assured, the foil cover works for my gas stove.  It fit perfect for two of the smaller burner but for the larger burner I had to cut out the center to make the hole bigger.  That's not too much off a hassle.
