What really like, is the handling of the machine in hand at work. Very balanced, crisp and precise in screws.
Here you never feel that the wrench is at its limit, particularly when screws forceful slow.
Battery charger also makes a very good impression and charges the battery (1.5Ah) in about 30 minutes back fully. The battery status can be displayed via a button right on the battery about 5 LED's.
All in all, this set is quite highly recommended, but if you're just a casual yet screwdriver to a super technology can not do without.
By the way I do with it also my wheel change. The screws are so powerful and fast in and out screwed so that only needs to be checked with torque even at the end.
