Product review (4 stars): Very good cooktop from GE
I was very happy to find this item at this price; it is over $200 more at Home Depot and Lowes.  I was looking for a 36 inch cooktop that would enable me to use 3 large pots at a time with room between each pot and this one fit the bill.

Pros:
price
fairly easy to clean
If damaged, easy to replace with GE's easy fit system (not sure if that's what it's called but essentially it means that if it needs replacement you can easily remove it and pop in another of GE's cooktops in the same size without having counter issues.
3 large burners, unlike other brands that only have 2
Power boil, melt and keep warm features, along with 2 burners that you can use either the inner smaller burner or outer ring larger one
child lock

cons:
Plastic knobs look cheap
gets dirty easily (but that's most glass cooktops)

Pro and con:
knob placement - easy to know which burner you are using (I find the side and rear placed knobs somewhat confusing at times), however, gets dirty easily from drips and spills
