Perfect hard boiled eggs! I no longer have to waste time peeling egg shells or worrying about leaving behind tiny pieces of egg shell. The egg boils fit perfectly in my pots and clean up is a breeze. You do need to spray the egg boils with cooking spray, or they will stick and have a hard time coming out. I can do 6 eggs at once which is enough for my small family. Side note: the egg boils CAN'T be used in the microwave. I only need to fill my pot with about 4" of water and bring the water to a boil. I would not expect perfect eggs the first couple of times because it takes a bit of trial and error to figure it out.
