This cordless screwdriver holds what is promised. Dier battery lasts very long. Even if I have for months makes also use him, he's still ready to use. The conversion from rod to pistol grip works well and simply. The device is very light, therefore comfortable to use. I use it for about 1 year. 1 star deduction is available for the trunk. Unfortunately, the bits do not hold it, so that everything always flying through each other during feeding and unfolding. The unit would I still buy again.
