I think I've had them for a couple of years now.
It's tearing on both elbows on my figure.
Some examples of range of motion. There's a warning that comes with it to not overextend the joints, so I try not to get too crazy with them.
What I was interested in was the fact that the skin folded and stretched. I didn't believe the photos so I had to look up some review videos to see it in action, and it does look and feel really nice. I think there are figures out there that have a better range of motion, just depends on what you want in a figure.
When I was researching these figures I also found a blog reviewer for just these types of figures.
But honestly, I still use photo reference for mostly everything; my figures are used as a last resort when I just can't get what I want from photos.
