Literally just got this range. It's for a  small kitchen in the basement of the house.   Location of the serial number for registration was ridiculous and frustrating. The knob for the dual zone was not clearly identified. Screws were missing to connect the power.  I already wish I would have selected something else.  As for cooking, heat-up time is average.   I guess it was a special for a reason.... I expected more from GE.
