Bests & Worsts Reviews from Amazon

This is a fraud, plain and simple. 1) After looking at the card with a magnifying glass, I was shocked to see: On the front of the card, the entire face was sanded off and silk-screened over. On the back of the card, it looks like someone took a Dremel tool and very carefully grinded off all the specs and serial numbers. 2) Real-world results copying to/from this card to/from Linux 2.6.33 SATA RAID array using the included card reader: 4536 files, 21GB, 4800 sec = 4.48MB/s unfragmented write speed; 1433 sec = 15MB/s read speed. Clearly a class 4 card. Not 6, not 10. 3) Package came with zero documentation. No instructions. No warranty info. No company info. If you think you are getting a "Lifetime Warranty", think again. I have no idea how they gathered such high ratings. I suspect most people just rate it high because the card works and have no idea that it is nowhere near class 10 and didn't notice the alteration. Or perhaps the vendor just started a bait and switch. The card *does* work for me, so far, it is just slow.
