Processing: very good. The paint / design is well attached, no paint noses, no bumps.
Terms: size adjustment made simple and quick. In particular, the magnetic lock is awesome as this typical skin-pinching on the chin effectively avoids (Close by stacking, opening by pushing).
The safety of the helmet seems also very good to. Corresponding test label attached. For detailed instructions here. Compared to cheaper helmets significantly better processing, thicker cushion impact. Above all, the chin straps are good. The magnetic lock is a hit.
Full marks.
