Pretty much within the first 20 minutes of owning them. I went to rotate Rambo's hand and it just snapped, but I find all the muscle bodies, or at least the ones Rambo and Rocky came on, gripped the wrist pegs tighter than the hard plastic bodies.
With Batman, I went to swap a hand and I had to sort of rock the peg to get it to pop out and in rocking it in ended up just snapping the plastic. I hope the DX either has better pegs or they do like the Predators and include a peg for each hand. The TDK suit figure is the worst figure I've ever dealt with for hand swapping.
Same here, Eric told me to do the same and he mentioned I was not the only one he got pegs for, you were part of the group
I actually do not attempt to swap my TDK BM hands now out of fear
