Avui 1 Not one week after using it (following the instructions) food began to get stuck. Tried it with butter, with oil, with nothing... Nevermind, I'm the end, ingredients get stuck and burn the surface (quickly, I don't leave the pan alone with the fire on). After a month, it has several burning stains on its surface and also on the part that gets in touch with the fire (there's no way to clean it properly).Really disappointing
