Now I have repeatedly had the experience that it is possible with the separator is just cold eggs well. At room temperature, a lot of yolk are me already got broken. If you want to set up egg whites, every scrap of Dotter's death, then you have to throw it all away and sacrifice a new egg. Once even a yolk has slipped through the slot (however not got broken here), but it was perhaps rather the egg as the separator? Bottom line, it is a okayer helpers, but it could be better.
