The quality impression is good but I wanted to actually cook eggs so.
The first thing I found confusing is that the egg boiler with electronic controller to determine the hardness eggs but as an accessory a water cup "old style" is delivered (with different water scale, depending on the hardness desired).
So I then read the operating instructions and, as stated, made the water cup full.
The first two eggs were, despite medium setting, hard as a rock, it has also taken subjectively very long.
The second eggs were also hard although the controller was set to "soft".
So, I then measured it accurately, and found that the kettle has "soft" needed at minimum setting 6.5 minutes to the signal - which is definitely too long.
In all modesty; I'm definitely not overwhelmed with the operation of an egg boiler - it just does not work as it should.
I have him returned.
