In use since now 6 months. + Funzt properly. + Hardness of the eggs can be adjusted reliably and finely. + Buzzer is loud enough + Most importantly:. The interior including heating surface is easy to clean! You can go anywhere with NEM cloth and the surfaces are relatively smooth, so that everything that was previously outside of the eggshells it and afterwards would remain in the egg cooker also can be reliably entfert again. I am very pleased.
