[COMPACT]: Each cordless screwdriver is wireless, lightweight, portable, small, and even pocket sized, to go wherever you go, whether working on your computer or electronics, doing work in your home garage, performing jobs at home, and more. [FORWARD/REVERSE]: The two buttons located in the thumb location serve to give you bidirectional 180-degree rotation accompanied by a self-locking safety chuck to maximize efficiency and accuracy. [FEATURES]: An extra bonus of this power driver is an LED light that is mounted below the chuck for a clear line of sight to your screw or nut in the darkest environments with the option to skip the hassle of manual turning and inaccuracy of insertion.
