In New state nothing is ever burned, and I was thrilled by the coating. Total repellent for oil and other food the Wok was cleaned wipe with 3x.
But:
After about the 10th application, the structure of the inner bottom coating has apparently changed by the action of heat, ie, has become rougher. Now really sets everything to the floor.
I kept the part anyway, because it works so, and you can live with the fact that you always have to scrub the floor clean (after use always be drunk with water, it dissolves more easily).
