Unfortunately, I get annoyed every time about this egg topper, because instead of the usual quality that I'm used to WMF I got a device which is limited to use only for the use made.
Touting the points with which WMF are almost the exact opposite of my experience.
The integrated mechanism is that it translates only with enormous effort possible the prongs to be driven into the egg. Here you have the teeth a couple of times but offset press in the egg in order to weaken the shell. It is otherwise not possible for me to lift the lid. In addition, the narrow handles in the fingers cut a pretty.
But from another noname product with the same look and feel as I do so is to work a part, and in which it was easy.
Maybe I've caught a Monday or product that in my product, the "teeth" are duller than usual. No Idea. Fix I can say that I have tested different eggs (shell thickness), my friend does not manage to open the eggs in order, and I have strong fingers - so it it is not! :)
Contrary to other readers, I can not complain about the opening size of me. Since eggs are perhaps opened in size S to close the yolk and perhaps have XL eggs to a small opening is rather the natural product and not on EI opener.
Personally, I can not recommend this product! It works, but there's a star. A knife can also!
