Product review (5 stars): should have popped for this years ago
I had to buy this to replace a kitchenaid glass cooktop that exploded on me.  I suffered with the thing for 20 years or so, trying to keep it clean ( glass and grease don't mix) and the enameled grates looked like hell.  The Bosch is a world of difference. I find it easy to clean, hotter, and more efficient in its use of space...and it has the large burner in the middle that works for grilling.  ignition is instant, flames are highly adjustable, grilles lift off for cleaning.  Since I installed it myself, I found it worthwhile to put in a gas monitor nearby...lets me sleep at night.
