I got this on Friday and with some of the comments on this thread, was concerned with replacement for the helmet. Mine came with the tiny magnet detached from the faceplate as well, which is pretty common with the Hot Toys Iron Man releases. Luckily, I found the small piece in the box and reattached with superglue (if you are an experienced IM collector, superglue is always a good investment for these problematic magnets). No other problems, but I was careful with the stand as mentioned.
It's a beautiful piece, and a nice variant on the Mark VII armor. The subtle nuances of the dark paints, matte finishes and dark transparent pieces really do give it a unique look. I haven't been able to put it down since it arrived. Looks best when photographed in a way where these details are visible.
