The letter 'D' on the packaging and SD card are different. Genuine cards never print trademarks incorrectly.

It has also been reported that the counterfeit card is slower write speed.
If you bought this deal, I suggest you report a paypal claim so you get a refund, and TinyDeal doesn't continue to rip off customers.
