Bolt of the screw head is well well and torque is hanging well.
Plus, minus, both are favorites.
Although it becomes a story of another thing, a driver with a large size bit has the same thickness as this driver, so it does not take the necessary torque.
Please make the grasping thickness appropriate for the bit.
Although it looks nice, the material of the insulating cover is so soft that it immediately got scratched or torn. It is used at the site, so it can not be used before durability. I will purchase another item again.
