In general, I'm a very skeptical guy when it comes to insurance. Before that, I was with DVAG. There I was told that they were independent. However, it quickly became apparent that only a few insurance policies were ever offered (and far too expensive policies at that). After that, I went to BestFinanz and was really offered the best price/performance ratio out of hundreds of providers!
Another very positive aspect was that I was not "talked into" any insurance policies. Saying "no" once was enough :)
BestFinanz keep up the good work!
