Make sure this fitsby entering your model number. Add 1/4 cup (Negg capful) of water to the Negg. Add your hard-boiled egg and snap on the top cap. Now you're ready to slip the egg out of its shell. SHAKE the Negg up and down with enough force so that the egg strikes the caps. Remember to take it a little easy, or you will end up with a slushy mess complete with shells.
