The two tips of the reversible mortise bits are designed with PH2 and PH3 to the needs of winter athletes. When not in use it is clamped in the lid; eingestekct below it is supported by a powerful magnet, as amended, and may - important in the snow - not really lost.
The ratchet function (reversible Speed) works well; Alternatively, you can turn it off as well.
Due to its brevity the palmrest area is low. Characterized the achievable torque is less than that of a screwdriver with normal long shaft. This is the price that must be paid for compactness. If not for weak hands but it is sufficient for the fortifications go necessary, also thanks to the good form with the corrugations. For the trip to the next "right" screwdriver it is rich in any case. Even better would be here but a folding or coupling mechanism for a lever been.
A little tight, it may be, when the area around the screw is not sufficiently free - because you have to pack up very far down, it takes just over the surface, in which the screw inserted, already a relatively large space. In my HardBoot bond no problem, but in others perhaps.
Conclusion: Anyone looking for a compact companion for possible emergencies on the road and has plenty of space around the screw, gold with this part. But who is looking for something with which he can fix everything bombproof in all positions will, which must be set slightly larger.
