Product review (2 stars): Fatal Flaw
Looks great at the store.  However, it has a fatal design flaw: the burners and the flame are far below the grate.  While it is nice to have that area to catch spills, the effect is inefficient heating.  Water takes forever to boil compared to our 16-year old GE electric cooktop (you know with the round, spiral electric heating element).  Additionally, it heats up the room since the heat slips around the pot b/c the flame is below the grate.  It doesn't make sense to me.  I called Bosch and they were like: "yep, the flame is below the grate and there is nothing that can be done."  If I hadn't spent so much time installing the thing, I would have taken it back even for a 4-burner.
