Mine was legit so I can't complain, however, others haven't been so lucky...
23 April 2019
I bought one of these from Amazon as a replacement after being sent a fake one from eBay. The one that arrived from Amazon is 100% legit and has worked in my Nintendo Switch perfectly with no issues whatsoever so from me it's 5 stars... however...
Looking through other reviews, reading people's descriptions and seeing the pics people have posted I can confirm that people are recieving the same fake cards from Amazon that I recieved through eBay. I don't think this is on purpose by the seller as mine was legit so I think these fake ones have slipped through at some point.
Some things to look out for if you do order a card and want to check the legitimacy of it:
1) The packaging they sent the fake card to me in is a white cardboard sleeve with a phone on the front next to the green android robot (an example photo has been uploaded by another customer in their review for reference).
Look thoroughly at the image of the phone. Is it blurry? If so then it's fake.
2) look at the card itself. Does the grey part of the card look really dark? And does the red part look like a painted layer on top of the grey part leaving a nanometre of a bump between both colours? If the answer is yes, it's a fake.
3) is the card a tight fit? Legit cards sit perfectly flush and will never have any fitting or seating problems. Those that do are usually fake.
4) how much data can you fit on the card? Can you store a few gigs of data onto the card but after a certain point does it straight up refuse to transfer any more? If yes then the chances are it's fake. Sometimes there are manufacturer faults in legit cards where they have faulty sectors straight out of the box but these are rare so it's best to assume it's fake. Further tests would need to be made to properly identify it.
What these scammers do is they use smaller sized cards and hack the software to read that it's a bigger size than it actually is. This was the case for my original card from eBay. The card would store 4gbs of data and then would "fail" despite saying i have over 100 gbs remaining. I first did an error test on HDtune to see whether it hard any bad sectors (it passed so it was fine there) then I did a read and write test which identified that I had in fact a 4gb card disguised as a 128gb card.
Just a few things to check when purchasing cards online to help those who may not know about this stuff and to help them from possibly getting scammed. Hopefully this all helps.
