Last year I bought an SD Card that turned out to be fake. There wasn't a straightforward return option for this item so I sent them an e-mail with a title "I this eBay? Because you go to eBay to buy fake SD Cards". Got a refund but I'm not going to buy anything from Amazon that is known to have this problem.

I just checked the item, still sold with solid 4.5 stars and occasional 1star reviews with pictures documenting that they also got a fake one.
