I bought it as an addition to impact and Shurik. I thought that the bits are self-sufficient, but no, they are only through a bit holder. The bit holder itself could have been snapped off in the opposite direction and inserted without pulling it back BUT for 900 it’s a sin to complain, I’ll replace it with a short magnetic bit holder. Has pros: Cheap set for devoltomaniacs Belt clip 360° Transparent case Reliable latch Has some cons: Landing in the bit holder could be done as on 887 impact and the bits are slightly longer but with the same fixation The latch is too reliable sometimes you have to pry something to open the case The bat is not so secure
