Product review (5 stars): Works great on glass cooktop
Bought a new glass cooktop.  Tried cleaning with a sponge or rag with poor results.  Read reviews about this cleaner.  Couldn't be happier.  Works great cleaning up spills.

UPDATE 1/23/15
Ordered another bottle at my wife's request.  This is the only product she will use on her glass cooktop.  Says it works great.
