I find the quality of the joints differs greatly from figure to figure (even multiples of the same figure).

My 8yr old son plays with them quite a bit, and for instance, I have a cobra trooper that is nice and tight all over, but another same figure from the same batch is completely loose in the knees and hips and therefore won't pose quite as well as the others. ~ just our experience.

Overall tho - I gotta say I am crazy-in-love happy with how these figures turned out and that Hasbro is even making them. It's like my own personal time teleporter came true! Wootolicious!
