Pan does not meet expectations

This set is with us in February in use. The pan has after the first use, a place that looks as if someone with a steel sponge rumgekratzt it, though I've actually only wiped with a paper towel. This site no longer goes away. Also, a "browning effect" that is known by other pans, can not be achieved with this pan to the same extent. First I pulled the returning into consideration, but the pots are ready all right, especially for the money. However, I would probably not buy the set.
