Even if it worked as well as advertised (which I doubt) most nuts or bolts you'll find in places where that big thing wouldn't work. On the aircraft I work on everyday, I'm struggling to think of ANYWHERE that would work. Most nuts and bolts are in such a place that that simply would not fit on them. Same thing goes for the multi-sized "dog bone wrenches" I've seen.
There is a reason why the big tool manufacturers go to a lot of trouble to make the walls of their box wrenches and sockets as thin as possible. As a professional mechanic, in addition to all my standard tools (and this is common) I've still got a whole drawer of "custom" wrenches and sockets which are ground down and/or bent in one way or another to get in, or on, or around tight/restricted spaces.
