A cooked-egg that makes perfect what is asked. A little water (to be measured with the measuring cup provided), and a few minutes later, your eggs are hard, soft or boiled. Of great simplicity, there are only water to measure, the rest is done alone and eggs are perfect.
Two mini minor drawbacks: the apparatus walls are warm after cooking, and the warning signal end of cooking is rather unpleasant.
Saving time, water and energy for successful egg every time.
