Can't really speak to the goo issue...all the pieces that were randomly inspected didn't have it. That's a new one. Could be a residue from the rotocast removal process that was not properly wiped down. It isn't toxic, so it is just an embarrassment rather than something I need to worry about as far as consumer problems.
The wires is a QC issue. Factory used the wrong ones, therefore they come off too easily. When you get Series 2 figures (IF you get them!) you will see the PROPER wire they were supposed to use in production. It is a thin and higly flexible thin PVC piece. You will also see that it is done correctly...tied through the part before assembly.
If you want to return it we'll take returns, but unfortunately every product I have ever worked on or seen has at least one problem. Murphy's Law of Mass Production. The wires were the Lab's issue. Zap-A-Gap, found in hobby stores, is bar none the best glue on the market. Use that if you decide to play Tim Allen and fix it. My suggestion to anyone planning to do this would be to throw the old wires out and get thinner ones.
Someone said this would not happen if we did not use a "third-rate factory". Got news from you. They are ALL capable of screwing up and they all DO. I've seen in at every factory I have ever worked with...EVERY one. Every figure I have ever bought has at least one thing, sometimes more, wrong with it. Especially when you start adding any extra details. The more complicated the product, the more things can go wrong.
Anyway, sorry about that. All I can offer as defense or compensation is a suggestion to take it back and exchange it, and if they are out, return it for a refund. I know that sucks, but what else can I really say?
