The batch arriving in Canada would be, by no means, 'a first batch'. While it's only just releasing there, it's been out elsewhere for a few weeks now. The concern is, to a certain extent, legitimate. First articles are always subject to more production flaws because production lines are just 'learning' how to process the new product. I'm in Product R&D and this is a common issue, it's only up to the companies to decide how much time they spend on full inspection on the first production batches. In the case of electronics, there's so much that can go wrong that not every single device can be tested for every single piece and bit. These issues are commonly ironed out as production rolls out and gets better with time.
