The little one is really good in the hand, after all, it weighs in spite of small size more than a pound. Ten different bits, a charger with a USB stick and two angular towers housed in a small, chic, practical metal box. There are short standard bits, which can also be supplemented and then also housed inside the box. When screwing a bright LED can be set as centered or diffused light, which is very convenient in darker corners, and the (switchable) direction of rotation is displayed in green. Red wirds when the battery weakens. In my test, he held about 50 Torx screws 4,5x50 long. Replacing the battery may be not. The device is a fast helper who brings everything you need to screw in his metal box, ideal for people who are not joiners permanently, but only once now and then one or four screws pure or want rausdrehen and want to stay happy even with a polygonal socket screw. I had are the device with a larger construction project next to the "correct" electric screwdriver - for the few special cases where I have handled in inaccessible corners. Went well! And if that's not enough: In Star Trek costume the device with its many lights and well as Phaser goes through.
