I bought this Bitbox aufrund the many good reviews. Initially, I was impressed by the number and selection of bits. However, after some wood screws 5 x 80 in pinewood with the T25 bits I'm disappointed because the bits are around a few screws. You twist in itself and makes further screws impossible. I will revert to my long proven bits of Wera Wiha or in the future. The experiment with an inexpensive set for me is teaching not save the 5-10zu genun. My T25 Wera bits are now after more than 500 screws still like new and reveal no wear. I'm just glad that I bought the box here and have not upped the ante in the construction market for 15 of the same box.
