Although I am satisfied with my Dewalt tool "fleet" in the tough assignments, does not even have this bit set DIY quality. How describe some other reviews, it's possible to use even for Mutti in the household, for professional use, it is not good. The closure is a horror that hakelige construction jammed constantly. The bits are removed due to the hard packed arrangement. Meanwhile, the 4. !! Bit (20 u. 25er Torx and PH2 and PZ2) easily broken at an average load. Here a normal Dewalt screwdriver was used, with the impact wrench I have not even tried. So weak is not even a 10-Euro Metabo set by OBI.
