I have this set Fissler Cookware Original Profi Collection 5 pcs. bought plus the three individual frying pans in 16, 20 and 24 cm. Altogether 8 parts: - 3 x Fleischtopf - 3 x Casserole - 1 x Saucepan - 1 x pan Of the 8 parts had 6 in the cold state a warped floor, so that the pot wobbled on the ceramic hob. In 2 of Wackelkandidaten the wobbling in the hot state almost completely disappeared. So there is still a proportion of 50%, where the pots wobble both cold and warm. I have checked the flatness of pan bottoms with a steel ruler, and all of them were hollow in the center (as it should be). Therefore likely they would have actually have to lie flat. The deviation from the flatness was at all the pots not very big - it fit about 2 sheets of paper (normal 80 g / m²) into the gap. Estimated as 0.2 ... 0.3 mm. On the flat ceramic (brand new box) but that's enough. In order to avoid an uneven stove, the pots I have also provided ground floor one another, with the same result. All in all for the price range an indictment. Before that I had, incidentally, this 7-piece WMF WMF 0711126040 Set Cookware Set 7-piece Gala Plus for about one third of the price. Since rattled even half of the pots, but overall significantly less pronounced than in the Fissler pots.
The second star I forgive the way that the pots are otherwise really excellent and not processed hum on my induction field also.
