have superior decided after a long me for this screwdriver because the is a screwdriver set equivalent, but much more space-saving and versatile. Firstly, only a screwdriver is in the box, which creates more room for other tools. Secondly, I always with the proper screwdriver. Mir has often lacked the right, either I had the PZ in hand un needed a PH or vice versa. That meant each time back to the toolbox and the right taken. Especially for installation work of this screwdriver is very helpful. Refer clicking them, correct bit and turn the screw, without having to change because here a very high-quality ratchet mechanism is still installed. And for the first time ever the right screwdriver included. Should the bit become worn, simply replace with a new one. Or there is a lack of Torx, then simply used. This screwdriver ratchet leaves nothing in terms of the hand nut little to be desired. Great product for good price, strong buy recommendation on my part.
