Bests & Worsts Reviews from Amazon

I have long purchased SanDisk SD cards because of the speed and reliability. However, my most recent purchase of the Extreme PRO 128GB card was unfortunately a knock-off as it was not recognized by the Black Magic Pocket Cinema Camera I bought it for. I searched reviews and indeed found another customer who got a knock-off instead of the real deal. SEE THE PHOTOS TO HELP YOU RECOGNIZE THE FAKE CARDS. I returned the SD card and received the real thing two days later and it worked just fine. I would suggest testing SD cards in the intended device immediately upon receipt, as the fake card was recognized by my computer -Mac- without a problem, and oddly showed a capacity of 134.7GB -red flag-. Had I simply stored the card I probably would have missed return by date. Amazon may need to better scrutinize their suppliers. I don't think they would knowingly sell knock-off products.
