Glass top is sound with no cracks or scratches (although "staining" and "heat" wear is evident) Auto lighting system works. All burners work well (front left has some damage to lighting system and sometimes needs to be lit with a lighter. It sparks fine, but sometimes doesn't light the gas. Repairable, but not by me) Approx Cut out size: 34 1/8x 19 3/4 Cooktop actual size: 35 1/4x 21 includes pressure regulator (see pic) Also, bag of bonus dials (see pic. The one thing I didn't like about the cooktop was the plastic dials. One will break about every 6 mo., so including the extras I bought).
