This Wrkzeug is worth every penny. Not for nothing is one of the best Wiha Schraubdendreher- and Bithersteller who also happen to be produced in Deuthschland. In direct comparison to the Vera-moving the upper knob does not move quite as round, for the gripping surface is better in the hand and consists of a good soft material that provides good grip.
The head dig in perfectly so far all tested screws, neither in nor twist wear at abrutshen were visible.
