NECA's Ultimate Gremlin Figure | Unboxing and Review 

I bought these when they came out. (I bought one for each look!) There is shoulder articulation, up and down, the joints are well hidden and can be very stiff. All of mine would not stay standing, even on stands, so they all went back into their boxes. The legs are over-engineered and will give you problems over time. Study other reviews on here before you do too much more with yours. Mileage with these figures is extremely variable. I still like them though and one day I'll fix the poses and display them again.
