I just received a tt from them. No troubles at all. Gunther was facing the discussion and their service/support was top notch, althought sometimes they don't reply fast as a lightstorm. To make it explicit, over 10 mails we exchanged 80% of them was responded in 1 hour time and the other two with one day timeframe. This sounds quick to me.
