Well I broke down and opened up the figures. For the most part they're pretty sturdy however there are a couple of loose joints and them. Han/Link's head flops about freely, I popped it off and stuck a piece of blue tack on the nobbin. Problem solved.
Threepio/Beaker's leg joints are also very loose. He stands pretty well but if I were to bump the bookcase I think he'll go over.
Chewie's Bowcaster and Hans's Blaster are also warped....but I fully expected that. The only lightsaber that's warped is Kermie's. That's because they packaged it goofy.
Otherwise I have no complaints. All the paint apps are solid and the details are pretty nice. If I get down to Disney this year I may pick up a second set just to keep in the box.
Here's a horrid camera phone pic of the figures loose.
