I noticed my right foot pivot was a bit stiff and wouldn't quite fold out all the way. Disassembled and found the same issue as Griffin. Fortunately judicious application of sandpaper appears to have fixed it up.
I tend to agree (either that or I've been very lucky too!).
As I said earlier, on other forums people are upset about missing the small silver paint dot on SW's forehead, barely visible swirls on the cassette door, and other relatively minor issues which I think distracts from major problems like Kup's laserbeak, unpainted feet or poorly assembled foot joints.
I've read, and this is pure speculation and rumour, that BBTS has clamped down on exchanges as a result of the number of MP-12s that were returned over minor issues. If this is the case, it could be argued that fussy collectors pursuing the 'perfect' bot have muddied the waters so much that those with genuine problems are now left out in the cold?
(Maybe this is more an American thing - their domestic shipping rates are pretty cheap so they can better afford to return items to the store? Given the cost of international postage from Australia I'd be thinking very carefully before sending anything back.)
Something else to keep in mind is that the number of parts that go into masterpiece figures is huge compared to the old G1 transformers which were made of 5 pieces and had 3 points of articulation if you were lucky. Simple blocky shapes are easier to make, harder to mix up and the fewer points of interaction with other pieces, the less likely you are to have issues. I don't buy the "good old days" argument at all - needs a much bigger sample size than one person's collection.
I'd be very interested to know what the overall defect rate is for the entire production run. These toys are being mass produced in their thousands but I'd bet only a small percentage of buyers are participating in the forums, and only a small percentage of those are experiencing or reporting problems.
