Warning - fake SanDisk memory cards on eBay

I ordered a SanDisk Extreme IV compact flash card on eBay recently and received a fake. I immediately suspected it was a wrong 'un and a quick call to SanDisk confirmed the fact. I then raised a dispute in PayPal which allowed me to claim my money back. The card on the left in the picture above is genuine, the card on the right fake. Although the poorly cropped sticker on the front of the latter is a giveaway in this case, SanDisk advise that a more reliable way of identifying a genuine card is that all four corners of the metallic inlay should be rounded - subtle but clearly observable in the picture above. Caveat emptor!
