Did you know that a third of the SanDisk memory cards being used on Earth are actually fake? A SanDisk engineer recently shared this startling fact.
Well, I have to check mine...
The article already mentions Ebay, but this is also very common on Ebay:
"P.S.: On a more personal but related note, here’s my experience in the area of fake memory cards: some years ago I found a great deal on a 1GB memory card at a store in China. Only after getting home did I discover that it was actually a 512MB card repackaged as a 1GB one — and returns aren’t allowed over there!"
