Very innovative. Allows you not to carry a whole set of sockets with you.
Good solid construction and quality materials. This model appears to work with a variety of screw sizes from 1/4" to 3/4". I will keep this in my truck in lieu of a full set of sockets for repairs. Innovative design, I recommend!
Pros
Universal Head: The universal head fits standard screws from 7/16" to 1-1/4" and metric screws from 11 to 32mm. Pins are free-moving handles for all hooks, eyes, bolts, nuts and other objects of different shapes and sizes. Not suitable for small screws. The included adapter allows use with screwdrivers, drills and sockets.
