The Severin EK 3127 egg cooker can hold up to seven eggs. With a power of 400 watts, it cooks breakfast eggs perfectly. Simply measure cold water with the included measuring cup, place the eggs in the tray, and cover. When the water has completely evaporated, an acoustic signal sounds. By piercing the eggshell with the integrated egg piercer at the bottom of the measuring cup, you can prevent eggs from cracking.
