Besides the fact that the bit holder is broken within me, I think the long Kreuzbits very practical. With the Torxbits I depended more blankets, without appreciable wear. The service life is thus quite regarded as "good".
Big pluses reaped me the 8mm and 10mm shock nuts with eject function. Of this I want a complete set, because I find this solution quite ingenious.
However, the set has a very powerful hook: The brackets nervous extreme! You get the bits out difficult and hard to get in. This reduces the fun very. In addition, slot bit lacking.
Addendum of 27/05/2015: I inconveniently run some water in the box, prompting some bits corroded. After I, lazy as I am, something MoS2 have sprayed into the box, I noticed the following day that the brackets are now as smooth as silk and the bits are much better to store. So if it's too hard: Good grease (höhö).
