With this purchase of the Best Egg Cooker you get a set of 6. When I bought them in the store for my mother in law they only came only in a set of 4, so this was an awesome find. These Egg Cookers are made with High quality food grade silicone, which makes them safe. These are also durable so you can have them for a long time. Very nice cool design. Easier than trying to peel boiled eggs. It takes me forever to peel eggs. Not only does it get annoying to stand there and try not to tear them up peeling them, it's a back breaker as well. Make sure to butter or use a baking spray on the inside of the egg cooker for easier egg removal. All you have to do is crack you egg into the egg cooker screw it shut and cook. Even better just scramble your egg, add some cheese, onion or whatever kinds of foods you like mix together then add that to the egg cooker. Drop in you pot and in a few minutes depending on how done you like your eggs they will be cooked. I myself went with scrambled with ramps and cheese. It was awesome. Also another tip I learned, only put enough water in your pot up to the rim of the egg cooker for best results. Your egg cooker wont tip over and get water in it. You get a Bonus egg separator with your purchase. If you are not happy with your purchase they will refund your money. How can you not at least give these a try. I bought these at a discount for my honest review of them. But also because I wanted these for awhile now.
