The cooktop has; good features but the bridge option does not work like my older GE cooktop.  The older one heated both round coils but also the spaces between the circles making an oval heating area.  This one only heats the 2 round circles.  What's the point?  I could just turn on the 2 burners separately for the same result.  Also, this black top always looks streaky.  I am pretty much fanatical about this cooktop and my last.  My last one was white and always looked great even after 16 years.  I clean this one first with ceramabryte then wipe off the excess with a damp paper towel, then spray it with either Windex or a degreaser spray and I still see streaks.  Wish the new models came in white.  Surprisingly white was easier to take care of.
