I have this unit now for a year in the interior design in use. Screws, drilling and hammer drilling in concrete, screed and masonry masters the machine without problems. The battery (2.0Ah) holds quite long - about one and a half times as long as the old (1.3Ah) batteries that I bought with more reciprocating saw and the Hexschaft screwdriver together. Charging the battery is really fast (30-45min) and at my pace ;-) always a fresh battery available. Impact drilling in sand-lime is excellent to 8mm, and well up to 10mm. Individual holes in concrete are also possible, but for more than two holes I bring extension cord and hammer. One point that it is important to consider when moving around screws in second gear: Screwed to a screw in second gear until it reaches the overload protection and thus stop the motor, you should settle before further screws in first gear the screwdriver from the screw and to find the gears of the transmission idling give the opportunity to each other. You screw namely continued immediately after switching, yells the gear, and I can not imagine that it will work well forever.
In summary, I strongly recommend buying this device.
