This is a great tool and beautiful simple design. It works well and is very satisfying to use. The grade C models are great value. I have the original too.
If you want a novel wrench that's fun to play with, this is an awesome wrench! It is plebty functional too, and handy enough in a pinch, though I find the mechanism somewhat awkward to tighten down on a nut, but it will stay where you set it. If you're buying this because you need a pocket wrench to do some serious work with, you're probably looking in the wrong direction, but if you love monkey wrench and want to add this to your collection and use it for minor tasks, its an awesome choice!
