hey there Xenon Hacks, while being "by Sandisk" and "ships from and sold by Amazon" (and Prime eligible) certainly lowers the chance of being sold a counterfeit or "scrapped series" MicroSD card, I can say from experience that it does not always eliminate the risk. I'm pretty sure you can google fake microsd cards sold by amazon, or something similar (haven't tried to, myself), and find many cases. Maybe Amazon have tightened things up, but I'll just say that I've had a couple of incidents that make it clear that either Amazon itself knowingly engages in selling dubious goods, or, more likely, are sometimes ripped off by suppliers in china, or middle men in the wholesale process. By "dubious goods", I'm referring to counterfeit/copy and/or sub-retail-quality scrapped cards which are made at the real factory but don't meet standards and are not meant to be sold, or cards from "unsanctioned manufacturing runs", where some rogue manager runs the factory in the middle of the night, producing cards that either all have the same serial number, or using a non-standard series (as was the case with a fairly well-known incident involving Kingston cards a while back).
anyway, the fact is, even brick and mortar retail outlets, if they have their own buyers sourcing these things in the PRC, could end up in a similar situation. so i'm in no way dissuading anyone from buying from Amazon. truth be told, i would say 75% of all items aside from food, paper products (toilet paper, paper towels etc), and other consumables, i purchase via amazon. they really should do a better job of policing the place though. recently some ass monkeys were selling "256GB microSD cards" for about $15-30, and of course the feedback was insane.. tons of fake 5 star reviews, and tons of 1 star reviews pointing out that the item was totally fake, and only held about 8GB or 16GB .. It was fulfilled by amazon, too. you'd think with the mountain of complaints, they would have acted swiftly, but instead the item sat there on their site for a long time. this was around black friday last year. some people said maybe they meant 256 gigaBITS.. but even then, that would be 32GB, and i don't think it held that much.. even if it did, that is HIGHLY disingenuous of both the seller and amazon, as the listing very clearly implied that this was 256gigabytes, and was a large-capacity card.
wow that went way off topic.
