The choice fell on this egg boiler, as it is to accommodate its oval shape to save space in the closet, and the purchase price speaks for itself. It is equipped with everything necessary for the production of a boiled egg - the Cup, the (actually steam operation) is kept below the cold water after cooking; the measuring cup with the required amount of water is measured for three different degrees of hardness of the final product in terms of the number of eggs; the "Pieker" which is located at the bottom of the measuring cup and the egg is angepiekt to make it during the cooking process (vapor) does not burst. After filling the egg boiler, the device is turned on and off selectively again after cooking. An acoustic signal, which is hard to miss, is heard at the end of the cooking process. During cooking excess steam from two holes escapes into the cover. It is advisable not to hang about his nose as possible! I have this egg cooker though only just bought and not yet so often worked with it, can and would highly recommend, see my headline this device!
