The cooktop is wonderful.  The design is so much better than my old GE electric cooktop.  This one has 5 burners that are actually usable at the same time.  With the awkward design of my old one, only 3 were usable at the same time...so this is a huge improvement.  Everything gets warm very fast and it fit our counter cutout perfectly.  The only issue we had was that we needed to conver this to propane using the LP conversion kit;  the kit had an incorrect part but GE corrected the issue and sent us a whole new conversion kit.   No complaints here.
