Product review (1 stars): Sorry I spent so much for something so unreliable ...
If it did everything it is supposed to do, I would be giving it 5 stars ... but it doesn't.  Purchased mine late May 2013.  Have yet to be able to use all 4 burners at one time.  The back burner behind the large burner will not work if the large burner is on.  Sometimes it will not even work if the large burner is off.  The GE repair person has replaced the entire top TWICE ... and I still have the same problem.  So, out of 3 tops, 3 are duds.  It is extremely picky about the cookware it will work with.  The magnet test means nothing. It isn't even reliable to use the same piece of cookware one day over another (may work one day and not recognize it the next)... in addition to limiting my use of the burners. The convection oven doesn't work all that great either ... but that is another story.  Bottom line ... save your money for something that works.
