1. The LED for illuminating the screw is matted and weak - suitable only conditionally for the intended purpose, in my view.
2. The bigger problem - the switch on the unit is not equipped with a control function, ie speed / torque are always equal. In order for a screw head is fast times demolished or a screw overexcited and destroying threads.
3. What may disturb some, is the lack of magnetization of the bit holder and the two supplied bits
Who can not be bothered by the above criticisms, can safely gather some interesting experiences with the device.
However, I will send it back.
PS just before a special promotion I think the thing with the increasingly frequent positive reviews also interesting (see comments).
