My sister gave me one of these egg cookers a couple of years ago and I broke it recently so ordered a new one. The best feature of this product is the shells always come off clean. I no longer peel an egg and take half the egg white with it. Follow the directions for your microwave and you will never be sorry. I cooked them too long once (12 min.) and that is when it exploded in the microwave and broke.Nordic Ware 64802 Microwave Egg Cooker
