I have long sought a wrench without battery. Rather out of principle than out of necessity.
Since I almost always screw at home or in the basement I do not need anything with (expensive) battery.
It's always in 3-4 meters a socket ... at 6 m cable is there an end to extra time Stoke.
After my little lightweight drill has given up with the I screwed long (broken chuck plastic) had now something new to screw her.
Not the lightest screwdrivers but with enough power - should be enough for all home applications. Today with Power Stage 6 screwed by 20.
Disadvantage is the poor usability for drilling: from about 4 mm in diameter have been drilling in metal issues as the drill rotates with. Tension-proof but does not go, since the inner ring from the chuck is so narrow and only a very slight ribbing has. Very bad that potential would be there.
Recommended as screwdrivers very - at the price ...
Update: The wrench is now for about 3 years in operation for domestic use without problems.
