The packaging is very nice, and for allergy languages, no explanation in French, but at least there was the Englishman. Will a manual really necessary? I'm not sure knowing he just put the dome on that of the egg, and then lift the ball up to the stop and let go.
Successful trials at once by putting the egg, not the egg cup but on the egg box, by cons in my opinion the fact of two "ball drop" is unnecessary and against productive;) a very slight shift in product positioning 2 areas perfect ruptures but few tenths of a mm from each other, and therefore there is some small pieces of shell.
Rather than take less, I preferred the original, it's not cheap, but at least it works!
