The picture looks like the stick-man is made of high-quality plastic or metal. I'm afraid to report that this is not really the case. It is fairly cheap, near-black plastic, I feel.
As far as articulation goes, it's spot-on. Oodles of articulation points and whatnot; only, some of the points are loose, making certain poses difficult or impossible as the stick-man just lowers his arm, or falls over by pivoting around his knee.
It does what it says on the box; but only that much, and no more.
