I heard that some older 21303 WALL-E models (LEGO Ideas #012) have a weak neck connection and that LEGO fixed that in later production runs, and that if I have an older WALLE I can contact customer support to have a "neck kit" sent over.
How can I tell if my model is the older or the newer version? There's nothing obvious on the box, and there is no information on the official LEGO website.
