For me, the first egg cooker, which makes very good so far (approximately for 4 weeks) his job. I need cutting fixed eggs, which is also very well establishes the unit with the appropriate setting. (Eggs the size M) It is very easy to use because the water is not to gauge exactly as with other devices. The hardness of the eggs to be set by the thermostat, which can well control the cooking time. Since I only need cut-resistant eggs, I have not checked the other settings for soft-boiled eggs. Possibly you have at large eggs (L), which take into account in the Gebr. Instructions recommended standing time. Unlike other comparable devices occurs when Severin during cooking from no water. ME very recommendable device.
