Product review (4 stars): Looks nice!
This makes the ugly coils on the electric stove look much nicer, though not a perfect fit to the actual sizes of the often warped coils of many old stoves, it's close enough.  And I've already ruined one by accidentally turning on the wrong burner and it turned black.....oops! Be very careful of that!  I just keep my teapot on that burner now anyway. (Do you sell individual covers?)
BUT overall is a great product idea for the kitchen!
