I've been using these cards for a while and have transferred many gigabytes worth of data back and forth with no problems whatsoever. The USB transfer rate is about 12 MB/Sec. I can't wait until the price drops for the 16 GB cards.

Now the picture shows a class 4 memoery card but the link goes to a class 6 one for ￡14.99. This is a great deal and this item is brilliant. At this price for 8Gb you are winning. The space on this device is excelelnt for the price you pay and also for the size of it.
