Product review (5 stars): Very pleased with this item!
Received product on time.  Just installed guards and they fit nicely and look great.  The black blends nicely with our black cooktop.  Purchased another type of guard locally.  They were "clear" but very wide and very noticeable!  Brought them back the next day.  These guards were as described and I'm very pleased with them.  A few reviews mentioned magnets came loose and strips melted.  Can't see that happening but time will tell.
