This is Not a Spinner and can most definitely be used on a glass top stove as well as a gas range. There are No Cracks and No Repairs on this pan and the cooking surface is nice with some utensil marks as to be expected with a skillet that has been around as long as this one.The Logo is Crisp and Clearly Visible as seen in the photos.
