Complete figure in great shape was only used for display. 

I would say the only thing to know with this figure (not just this particular figure it's all of them) is the arms pop off quite easily during transformation.  It's just a ball joint so there easily pop back on.  I did put some of the not permanent joint tightener on them so if you do want to build them up with some clear nail polish or something just clean the ball and socket first with some rubbing alcohol.  If you using it mostly for display it's not a issue.
