For years I made hard-cooked eggs by putting them in water and when they started to boil I would time them for 10 minutes. I recently received an electric egg cooker as a gift. It is so easy and convienent to use. I can now make hard-cooked eggs, soft-cooked eggs and poached eggs perfectly every time. It beeps to let you know when the eggs are cooked. I thank the person or persons who developed this wonderful cooking tool.
