i never take the chance. McFarlane destroyed my trust with figure companies and i immediately dunk every single non-high-end figure in hot water as soon as i get it. right out of the package. i don't move anything on them before they're good and soft so i can loosen any potentially stuck joints. since i started doing that, i don't have any broken figures now. might not be a bad habit to pick up.
Sounds like a pain in the arse but I'll give this a go.
