After I was rather dissatisfied recent years with DIY screwdrivers (too big, too heavy, too little torque to short battery life) and also the not so cheap Li-ion screwdriver from discount after one year has little battery range, it was time time for a professional device. I used an ELU cordless screwdrivers in tough conditions, which has dwarfed with only 9.6 volts everything, unfortunately there is no longer ELU but I wanted to be of comparable quality. At first I was interested in Makita but that I do not insets the cordless screwdriver daily, Makita me was just too expensive. From the green Bosch appliances I'm not convinced and the blue series is priced interesting. The Hitachi has addressed me by both the price and the technical data, a lot of torque, short loading times, to 2 batteries. I remembered that my local equipment dealer had converted its entire electric hand tool range of Makita on Hitachi two years ago, so for me one more reason to be expected here craftsman quality. I was not disappointed so far, the cordless screwdriver is comfortably in the hand, is light, compact and relatively quiet. I have so far only Decking screwed (5x70) but notice here already that the speed does not drop the screw, as opposed to the 18V power screwdriver from discounters. The device has an overall very well-made impression can be controlled well and the engine brake is great, the drive is also available in 2nd gear immediately. The carrying case is relatively easy but I eh not use the one that is in doubt, the device loose in the trunk. How long the battery lasts I can not say, of course, but I submit a strong buy recommendation,
