Yes folks, unless you are absolutely sure about the vendor's reputation, I would say that most of the flash memory cards sold on line are fakes. This really is a huge problem since most of the buyers are unaware of this. So, what exactly is a fake? These are usually inferior graded flash memory that has been used to "upgrade" to an apparent higher capacity card with a name brand manufacturer's sticker on it. This type of counterfeiting is no different than selling bogus Rolex watches at greatly discounted prices. But the bigger and more insidious problem with bogus flash cards is that the customer is not aware of it, unlike the phony Rolex's where the buyer usually knows that they are knockoffs. The card may fail right away, or as more typically happens, they will work for a while and then fail...leaving the owner not a clue as to what went wrong. I purchased a Kingston flash card before our trip to Asia. Everything was going fine until we had snapped just over 100 photos. We were in Shanghai, right after our run through of Japan. The camera would not snap any more pictures indicating that there was a problem (I don't remember the actual message). In addition, we couldn't view any of the photos we had already taken. We thought at that moment that disaster had struck and we had lost all of our precious photos. A savvier member of our traveling group suggested that I might bring the card to photo/electronics shop, as they might still be able to retrieve the photos from the defective card. So here I am running around Shanghai trying to find the proper place to have surgery done on our flash memory card. We finally found a place, but it wasn't cheap. We paid $145 to retrieve the photos, and except for a few, we were able to salvage most. Considering what we spent for the trip overall, it was worth it. But it was also an expensive lesson. Before entrusting your photos to a flash memory card, make sure that you have purchased it from a reputable dealer. And regardless of where you might have purchased it, test the card before using it. There a number of software applications you can run from your pc to do this. I now use "h2testw" to test my flash cards after purchase and before using. It's a free download, just google to find it. You can also get more info on this problem by googleing "fake flash memory cards". I'm posting this on Amazon, because of a previous poster reviewing and reporting his discovery of the fake card he received from this vendor. This vendor is still here, and apparently still selling this memory card even after the buyer reported it to Amazon. So, let the buyer beware, and do his due diligence when buying these items.
