I got an ongoing dispute regarding a "damaged" item, it was posted here back in January. The buyer (in China?) is obviously unsatisfied. I'm not sure if he returned the item now for inspection, in order to file an insurance claim, I would accept/open it.

To the OP, I'd say no, let someone else be the guinea pig

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
