It's my understanding that a soft clear would be obvious at assembly stage. That said; who really knows because JJP isn't being transparent about a darn thing.
I thought I read somewhere in one of the many threads that a number of games show pooling on the first unbox. not after 100 or so plays. Since I haven't been crazy enough to be bitten by this issue ... I'm only speaking from the multitude of threads on this issue across all the vendors.
Personally; I feel JJPs QA assembling is just simply trash / non-existent. They just throw shit together and ship it with very little care about the overall quality of the product. I'd bet there is an incoming quality check they could do to weed out these PFs. But they are more interested in taking your money rather than doing a good job.
That said; I wouldn't want to risk a 12k pile of cash on my understanding. The best thing to do is just cancel your order demanding a refund for the deposit.
