Received mine a few days ago. Once I opened the box I noticed that a small piece in the left arm armour is missing (dont know how this is called). It's a pity since the figure is brand new. But it doesn't matter to me much since there are three of them inside the box. Now really I didn't expect that for a figure that price.
Happened to me too. Superglue. I can't even tell which one it was. I actually got mine with a loose left arm, it took me almost a year to pop it back in correctly.
