Product review (3 stars): The magnetic stripe came off easy
This gap cap looks really nice on my black stove top and fits perfectly.  The color of the picture looks grey but the real unit is in fact shinny black.  It holds itself down by a magnetic stripe which is supposed to stick onto the edge of the stove.  All that is fine except the heat from cooking slowly loosen the glue between the stripe and the back of the unit.  So every time when I lift the unit out for cleaning, the magnetic strip stayed on the stove.  This goes without saying that the gap cap no longer secure on the stove.  It does do the job of preventing stuffs from getting into the gap.
