I was drawn to the different print patterns on these from many of the other figs on the site.  They might be UV printed?  You can feel a raised texture on the torso, legs, but the quality seems pretty good to me.
 
The common issues with the knockoff figs can be a little bad here.  Some of the torsos and legs I could not separate except with a good amount of force.  Some of the legs are very hard to move, and the legs fit pretty snuggly on studs.
 
If you are looking mainly for display and infrequent posing, you shouldn't have any problems.  If you are constantly moving the arms and legs, you might get a little frustrated, but for the cost it's still not too bad.
