This product was dead on arrival. People online say Amazon has been known to co-mingle with third party sellers and I've drawn a bad hand on this one. Absolutely fake. I'll be either charge backing or finding a way to get a refund through amazon. An absolute scam like this shouldn't occur. I will never order another SD card off of Amazon. The 128gb one I ordered is still going strong and I bought it first.
EDIT: Amazon sent me a fresh one and it works well. All good now!
