Bought the screwdriver for my wife, as small and portable, and because a replacement / NotgerÃĪt in the house can not hurt. For (dis) assembly of cabinets, he is good in any case, enough strength, the small machine anyway. Once we have charged him, so far he does not, so unfortunately not specified by me to battery life. Is also nice that you can turn the handle backwards. The charging station, which simultaneously serves as a bit holder, completes the package. My father has the same screwdriver and is also very satisfied.
