With this mini-screwdriver can be very small screws with a flat slot easily rotate in both directions - though only alternately and only one screw per operation, but that does not mean no serious limitation, especially in relation to the price, and otherwise, the manufacturer claims neither.
Of course, one must expect from the apparatus is not too much: With its maybe 2 mm large flat blade can now be solved once no fixed centimeter thick cross screws, but this impression is trying manufacturers also did not wake.
In handling the device without any problems. With a little practice you can regulate speed and torque continuously.
The only real gripe is the incorrect designation that could lead to one or the other but astray: Contrary to the name you can not screw with this unit PULL! Solely for turning screws it can be used, but that is no mistake possible.
For the transport can be the Victorinox miniscrews "puller" in the hand carry (Caution, risk of loss - he is really very small) screw or on the corkscrew of a Victorinox pocket knife with corkscrew. The latter is likely to be the preferred approach for most users and farmer users.
All in all I am delighted with my new mini screwdriver and always take him with me!
