Absolutely bad buy

I "had to" give one star because there is no way to choose zero star!
I bought the egg topper, because I wanted to have a clean cut.
Result: The egg topper slipped on the egg and does not intersect.
It works only with pressure (and with finger pain), so that it at all does not make clean step. In addition, the hole is too small and you need to extend it with your fingers.
Exactly what I wanted to avoid!
I guess with the other method to stay.
