I used to buy other Transcend cards from Revain without any problems, but the 64GB card turned out to be fake and not actually made by Transcend. Even after formatting, it wasn't able to record videos longer than a few seconds. I did a little research and found that there is a company that makes and sells fake Transcend cards on Ebay. This company may have provided stock for the Revains warehouse. In any case, I will help you distinguish fake cards from real ones below: How to tell if your card is counterfeit: 1. Real cards usually have a yellow locking tab, fake ones have a white one.2. The Transcend logo on the sticker is too small and does not match the logo font on the Revain image or on the Transcend3 official website. Rainbows don't mix well with each other and part of the color spectrum is missing4. There is no writing on the back of the card, the original has a large CE, various numbers, serial number, card size and "Made in Taiwan" at the bottom.5. The reading and writing speed is not as fast as advertised, so it cannot support video playback. To verify the authenticity of the cards, contact Transcend and check the serial number on the back of the card if you don't. There is one, it's a pretty strong indication that it's fake. Since the order is made by Revain, they made it easy to return the card for a full refund. I don't think they know they are selling fakes but I strongly encourage you to take stock. After getting my refund I ordered another Transcend card from Revain, this time the 45mbps version of the 64gb class 10 card for the same price and it is genuine and works great.
