Rust - and that after only 1 month

At first I was of this pots over excited and could agree to the text described here only, but after about a month, unfortunately I had to realize that (flight) rust spreads on each of these pots. Therefore only 2 stars.
In addition to pots of Schulte-Ufer I still have some others who are much older and not begin to have (and were even cheaper) this problem.
After such a short time to be set already Rost testifies not of good quality.
