So two weeks ago I get my FP Xfire set, and I'm a kid in a candy store. I immediately notice these cracks on the figure. So I make arrangements to exchange it. I get my replacement in the mail today, check the troubled area, and it's all good, so I begin folding down the arms and now this! See those vertical lines above the pins in the elbows. Yeah those are cracks! I can't win! What really sucks is how awesome the figures are! I want to buy a 2nd set, but there is no way I will if I end up stuck with this! It's not the sellers fault, but I can see where he'd want to wash his hands of it. No I'm not transforming it wrong. If I was I'd eat it, and this post would be to warn others on how not to do it. But I'm doing it correctly and the cracked joints have never been moved by me yet. If you transform it properly the arms will bend at the ball joint, which they did. I wish FP didn't use these cheap ass hollow pins. They are tons cheaper cost wise over solid pins, but they expand under the pressure it takes to insert them. -=FINALLY=- Considering I pre-ordered this thing in march it sure was one hell of a wait!
