PUT YOUR MONEY WHERE YOUR MOUTH IS! After living with this cooktop and seeing the quality(yes knobs could be metal) I ordered a complete GE KITCHEN SUITE. (SWAPING OUT MY OLD GE KITCHEN OF 18 YEARS) AND A GE LAUNDRY COMBO(SWAPING OUT MY 10 YEAR OLD MAYTAG COMBO)  ALL DUE TO THE SATISIFACTION OVER MY GE COOKTOP.
