Perfect hard boiled eggs! I no longer have to waste time peeling egg shells off eggs or worrying about leaving behind tiny pieces of egg shell. The egg cooker fits perfectly in my pot and clean up is a breeze. You do need to spray the egg cooker with cooking spray, or they will stick and have a hard time coming out of the cooker. I can do 6 eggs at once which is plenty for my small family, so I only need to do it once. Side note: the egg cooker can't be used in microwave ovens. 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.
