Product review (3 stars): Nice, But Vertically Challenged
I have an old gas stove with cast-iron burner grills.  My old covers, the small-sized ones wouldn't sit on the surface of the stove if I left those on.  The front ones did.  With this set, they're all sitting on the grills, hovering above the surface of the stove.  They would probably fit on the coil of an electric stove all right, but the gas stove...  stuff can still get under the edges, so you might want to look for a 'taller' set.
