Maybe you didn't notice. I've purchased many products from Amazon that were fakes. The worst was a SanDisk SD card that died with my honeymoon pictures on it. Turns out it was a knock-off, missing some SanDisk factory hot stamps. It came in full retail packaging, with user manual - it looked completely correct if you didn't know to look for the hot stamp on the back. By the time I figured it out that vendor was gone from Amazon.
