I've attempted to take two DB trains this year, while travelling both through Germany and with Berlin as a destination. In the end there were seven trains, and 8 hours extra lost travelling with DB. My compensation was pitiful.

Living in the Netherlands (not native Dutch) I will now rather fly than take a train if it means that I can avoid using DB.

For contrast, tomorrow morning I am heading from the Netherlands to Paris with a train (non DB), and don't really expect anything but a pleasant and smooth journey.
