The quality is top, but I have 2 attempts needed to get a sufficient pan. Specifying 28 cm is misleading because the pan is UP! 28 cm in diameter! The floor has a diameter of 21 cm, the base pattern recommends a hotplate up to 22 cm. The shipping container seller * buy * momentum was lousy sloppy, too much of a carton, a loose slipping product box in it, and the whole glued makeshift, a miracle that the glass cover is heilgelieben. But it can indeed this wonderful pan nothing.
