strong quickly and forcefully, ..and that's his problem

to take one front: the impact wrench does exactly what he should loosen the screws or tighten.
for all afflicted back there is another relief when changing a wheel, for example, not to break loose the wheel bolts with wheel cross or long lever or tighten.

I miss on the device clearly a possibility of torque setting. However, mine is (if I looked right) worth not ca 50 difference to the next better model.

The on-off switch is like on a drilling machine or a cordless screwdriver is a "button". However, this button without any speed control, so a pure input, switch.
Since the screwdriver reaches a fairly high speed, which is negative along with the 0/1 switch in my view, because if you have a screw attached mistakenly scheif, then the thread is quickly over.
On the button, R / L, ie the direction of rotation. However, this is on the front surface, so that the finger pushing the button, anyway covers these letters. here I would find a solution, as with most cordless screwdrivers or torchs, where you / has a switch left right, better.

The case comes in a plastic case. as with most other electrical appliances in a suitcase, you get the device after having once drawn aside the cable line, no longer simply housed in the small suitcase.
The enclosed sockets are stable, but I guess not fully surfers fit what is not to be expected at the price.
The impact wrench himself makes a very strong impression, the cable line is thick and soft isolated / flexible, there's no quick damage or broken cable expected.

due to the combination of price and strength there 3 points.
the torque control can not presuppose in this price range.
the thing with the button and the high numbers of revolution give basic 2 points deduction.
