I am using it to remove the special screw of the foreign car. Although I felt it was hard to get a little strength when turning screws, perhaps my way of using it was heta ... but I can use it without problems.
It is surprisingly hard to use, so it can only be used for emergency at the destination. Either screw fastening or loosening, when rotating with force, since the shaft is not fixed, the fit with the hole is released, and it can not be tightened / loosened well.
I am using Torx as a handy tool of a pretty harley. Since the hardness of taking out can also be adjusted with screws, it is very handy because it will stabilize even if you put it firmly if it is firm.
