Product review (1 stars): junk
After 2 months I pulled the stovetop extenders off to clean under and around the stove. When I pulled them off, the magnet which holds the extender to the stove, was cracked and broken, I assume from the heat. Half of the magnet remained on the extenders while the other half, made up of broken pieces, stayed stuck to the stove top. Also, after just a few weeks, one extender wasn't sticking very good anymore and would constantly spring up slightly from it's level seating. I assume again the heat from the stove weakened the magnet somehow? I don't know. I do know, however, that these things are cheap junk. LOOK ELSEWHERE.
