Bits are useless. The square ends don't line up with the shaft, they wobble. Rather pay 1-2 euros less. The T-handle is good. it is adjustable like a chuck. There are no internal steps like other TH cranks which are PITA if the bits are the same size as the steps. The lining consists of 2 parts with a V-neckline on each side. Move the slide knob to the center to tighten/loosen the chuck. The pole section can be easily removed when you need space or speed. But also stays in place if necessary. Everything is fine with a ratchet, just 7-8 teeth and a lot of play.
