Quite nice, but not really convincing

I have tried the device initially on one set of tires, I had assembled with attention to the correct torque.
All screws went down very well and also up again.
The impact wrench is as I expected it this noisy, smells directly metallic.
In a second car he got solved not a single screw. Tires were previously assembled in the workshop.
Hand the screws with moderate effort and a normal for a household hub were quite solvable, but not for this device.
Positives:
-dreht screws out faster than is possible by hand
negative:
overwhelmed -relative fast
-Lärmpegel
-smell
