I need to sit down and have a good fidget with mine.
I bought it while on holidays and flipped it between modes a few times in my hotel room.
The joints for articulation on mine were all fine but a couple of the pin joints holding armour flaps on were very loose. The yellows were also quite mismatched across the different surfaces of the figure, and otherwise seemed quite light for the character. My feeling was that it should have been a slightly deeper shade of yellow.
Aside from that it seemed to be a fairly good figure.
