SEVERIN (EK3136) Eierkoch-machine aluminum black The Teflon-coated heating surface of our elderly round Krups Egg Cooker (350 W) was, among other things visually no longer ok After much back and forth we og Eierkoch- "machine" (400 W) (good store for the successful design and compact dimensions bought in a kitchen drawer). After several attempts now found the right attitude for not firmly boiled eggs the dial. Amount of water need not be measured in advance (... before an advance), unit will beep when the set degree of hardness is reached after about 4-5 minutes and then must be switched off. Lid is opened, max. 6 eggs are on a somewhat "lümmeligen" holder (hopefully keeps the long!) With good grip to take out. Positive: fast cleaning of the equipment, also of circular coated heating element (only about 9 cm diameter in the center of the base) .Because of our hard water, another selling point.
