The Bosch battery Schreiber (Bosch IXO cordless screwdriver Home Series 4th generation) is sometimes not a cheap thing, but behaves accordingly. It is small, handy, extremely pleasant with the essays and the battery seems to be super. Clean screws he does everything where you turn puts him without hesitation. I have the torque control device moreover bought, so he would not be too aggressive deals with smaller cog, and is also really great.
It is expensive, yes that's right, but you get the expected quality. Truly a great and handy thing!
