The opinion of another client (notice authorized by amazon) focuses exclusively on the lack of seriousness of tefal because of the same problem as mine ... But since my opinion more advanced finger seriousness of this amazon This product, amazon has censored for being too outspoken. Here is the 2nd version (where only 8 words differ) who nevertheless fully respects the slogan "Be frank" about Reviews: Grading product itself: it's a pretty heavy skillet but possibility of induction compels! Its weight gives it the impression of serious ... If we care not to heat it too much empty for too long not to use metal utensils (its non-stick coating, like all other , is not good to ingest and loses effectiveness if scratched and worn) and storing it without the wear prematurely, this stove that quality deserves 5 stars! But before you order 2 of these 30 cm Tefal pans, and without knowing the vendor involved, I had read the 6 opinions of customers (already there, there are too ... 5) who received / the pan (s) dented (s). I chose amazon and 3 days later, the two pans that I received were not round! And deformation in the same place, more like a manufacturing defect as a shock. So the only star I give is to share between Tefal and amazon: half a star for the manufacture where tefal on this one discredits the ISO standards to which the mark is subject, and a half-star for distribution where amazon knows its stock is faulty but tries to sell to customers complacent! This is unacceptable! Aside from a small missed recently, this lack of seriousness wonder amazon has a service, for one, usually flawless! (For once we can write a review on amazon ...) The exchange was very fast and perfect: the 2 new stoves received are perfectly round! At the next customer to receive the stoves I returned, perhaps? Average: 3 stars.
