First, the shock was great when the pan apparently did not work on the large induction field. This was but the fact that they did not have enough contact on the largest field, on a smaller field it works beautifully. Here should be noted that only the individual protrusions are in contact with the support surface, because the pan bottom is not smooth (can not be seen from the photo).
Otherwise, a wooden handle would be precisely because of the good thermal conductivity have been desirable (hence -1 Stern). Produce such will be a new project.
Conclusion: The pan is doing what it should, delivery and quality excellent.
