Summary: i've had this cooktop for a little over a year. a chip appeared close to the speed cook coil. a crack has gone through that coil. i have two long cracks now going through this cooktop. i can't even use the speed cook burner any more because it started smoking and caught on fire underneath. i believe the glass on this cooktop is too thin for high heat and every day use. maytag will not replace it either, so i'm out over $700. waste of money in my opinion.
