Bicycle or motorcycle, because a variety of drivers to such as home appliances repair is required was purchased as a tool that can be aligned for the time being one through.
If you use common in even higher home accuracy of the driver bit socket it is content enough too. Since the tip of the bit is properly magnetization does not have things like screws fall.
The lack of a set, 14 mm or more of the hexagon socket and 8 mm or more of the hex I think that is good going by adding buy in preference because more large force becomes necessary.
Ratchet handle, because the extension is attached is convenient and can both use of the usage and normal size, such as a stubby driver, may be a large torque is better to prepare a separate tool for this tighten if necessary not.
Case also solid and sturdy.
