>>7990141His upper chest is held together by a quadruple nonreinforced 6dof pin joint assembly, which causes his shoulders to droop at the slightest provocation unless you find a way to jam his wheels into his torso, which only does so much. The clips that hold those assemblies to his chest also barely work and will come untabbed every time you try to pose his arms, pretty much requiring you to retransform his chest as they sure as shit don't go IN easy. His elbows also can't bend forwards since they are mounted on the back of his hood pieces like the 2010 deluxe. His shoulder armor is also unpainted grey plastic and cannot fold up correctly due to major tolerance errors, causing most people to incorrectly assume it's kibble and tuck it into his back.
The panels his shoulder cannons connect to will barely stay tabbed to his arms and will also come undone at every opportunity.
Also, every mechanical component of his upper body frame is made of unpaintable plastic, so you can't even mod it to work right using plastic cement.
He singlehandedly put me off of collecting the 07 Autobot cast in MPM. Jazz looks meh with his huge piles of kibble on his shoulders and at this point I could care less about Ratchet. If he's absolutely phenomenal I MIGHT pick him and Jazz up.
TL;DR his upper body is a complete and total unforgivable trainwreck that doesn't work at all outside of the CAD program it was designed in.
