No question, the tool has been thought out, functional, versatile and high quality. At least in terms of the stakes. Even after repeated use is not yet detected no signs of wear. The clamping of the inserts in the grip is much too weak for my taste. Unfortunately, it happens for some reason at some combinations of applications and handle to the fact that the use by the handle assembly from falling on the way to the screw head. This makes the tool for difficult locations (head, assembly platform, etc.) completely useless and annoying incredible at the workbench. Here is the manufacturer definitely still need for improvement.
Nevertheless, a (limited) buy rating.
Addendum: you have to be strictly observed in the tool, always accurately matched insert the screw head (slot!) To choose. The tool steel is extremely hardened. This has the advantage that it does not come to cancel the tool at an incorrect use - however the screwdriver head can bend.
