I have to say that some of these complaints are BS. There are bound to be accidents. The Link things IS freakish because this is the first and only case I've heard about such a thing. Maybe that store just got a bad case, it happens. But series four has no wide spread problems. The joints have been altered so that if they are sticky, they are chunk enough not to break. And if a joint is stuck, do NOT stick it in the freezer because that is not a Palisades recomended fix. The real way to fix it is to pull the hand away from the arm a little so that the pin loosens a bit, then try. Also, try keeping your figures in a cool place. If it's hot, they will melt and get sticky, they are freaking plastci, duh.
Too many complaints that really are valid here. The only real problem has been the series 1 lab set wires, and that WAS a freakish mistake by the first factory who got canned because they made too many mistakes.
