Quoted from Zablon:I don't know, seems like it would make sense to play the hell out of one of them (not going to customers) to check for any bad parts, before going and making them all. This particular issue isn't a few years of play, this is a few days. It looks bad. The whole "i've been in this for decades and it is just how it is" doesn't cut it when you are dealing with people who aren't pinheads who just dropped 8k on a toy. Pride and quality is a lost art these days.
It's a general QA issue in manufacturing. You get a huge shipment of parts, you test maybe 5% of them, and accept/reject the whole shipment based on how the few randomly selected parts perform and match the specification. They don't have the time to really test each and every single contracted part before it goes to the assembly line.
All large-scale manufacturers who rely on outside vendors operate like this.
