I have an egg cooker - it only makes 7 eggs at a time, and you have to puncture each egg before you put it in the little machine but I never have trouble peeling them. My mother would say it is because you are making them for company. Her eggs came out perfect when she made them for the family or putting the eggs in a salad so it didn't matter what they look like. But make them to take somewhere or having company come over - then the little buggers hold on to those shells like crazy.
