I ordered this in a frustration free for, I don't really know why, and to my surprise the package was already open.Amazon is trying to make my life so much easier that I won't even need to open anything anymore. /ironyMaybe someone messed with my card, maybe not, but I'm never ordering anything in frustration free package.I'll test the card and update the review.Update:After testing the card and contacting Sandisk about it, i'm able to confirm that the card is authentic.The 3 star review reflect the packaging. I might not use it next time.
