The Zugluftstopper served its purpose very well, he keeps the cold air from outside from super. The stopper is also not as easy as some others, he is not so easily drawn away from any pets;) He is responsible for my door, unfortunately a little short, but the length specified is correct. Nevertheless, he keeps drafts from already very good and the floor in the hall is not quite as cold. Thank you very much, anytime again!
