Love this cooktop, heats up faster than Bosh.  Beautiful design like beveled edges.  The only downside is the lights are too bright and blinding, needs to be red or dark blue light. And beeping sound eveytime you turn the nob is too lound and kiddish sound.  Modify sound to normal beeps.  Maybe interate a user button to countrol sound volume.  If GE did this this stove would rock!   Im an enginner and  Love GE products!  Love this stove but make it classy by changing sound and brightness of light!
