I would challenge them. They did the same with my Black Widow PF. The magnet inside her arm was imperfection so the switch out hands would not stay in place (loose). They said it was fine. I took more pics and question if its actually normal. I also said I am one of there most loyal customers who spends $$$. They finally accepted in and I'm on the WL for a new body.
Thanks for the info. I will play hardball then and see what happens. Worst case senario is I return and keep buying them until I get a good one on their shipping dime at least until they sell out.
