Hmm I heard that the production house wanted to use a certain part (one made in china)...then was told no that this other part needed to be used (one not made in china)...which caused the delay because that part needed to be ordered and shipped to them...and now that part that they were told to use isn't working and they are being blamed for it.
You are living in the past, the production run has been over for weeks, there are more pressing issues atm like the recall, and getting the boards back out. I am quite certain IF there are any more batches that any production issues would be seriously looked into at that point. eg in NSW where the Drillbit board is designed there is

My point was, the original delay due to substandard parts...and rectified with better parts is not the case, someone made a decision to change the parts and the new parts are faulty (the ones that were supposed to be better). So what were the original parts and what were they replaced with, and what made them substandard.
Meaning not only was there a delay to change the parts but the parts that were gotten that caused the delay are faulty.
