Like the other reviewers have said: The sound quality is very poor, especially on the 1st CD you can hear not what the participants say. But later, when you hear some extent, it takes a lot of patience to zusammenzubekommen from the various answers something useful. I ultimately did not belong to anything, because I ran out of patience. Also I did not like the instructive tone of the seminar leader. For me, it came on so that he deals with the participants from the top down ... That would go in my opinion, also respectful and appreciative.
