it's a blessing to believe in law and law enforcement. If everyone does that, we will see much less crime.

That said, there's a much more likely answer to current situation than scam. The chips do not work well, at least not stable enough. If it is just board issue or software issue, it will be fixed already, considering 2 weeks have past. Moreover, board/software issue is a small issue, so they can admit it easily. Only the chip failure makes them reluctant to let us know. They just tried everything they could to buy sometime for them to fix, if it is fixable. just wish they have not spent a lot in ordering large number of unstable chips already. Chips may work initially and passed their tests before they realized they do not work stably.
