It worked fine for a week, then the write speed started to become erratic. Sometimes it's fine, sometimes it slows to a crawl. Less than three weeks in, copying a 300 MB file took 30 minutes. A few days later it was fine again.
I've tried removing and reinserting the card, rebooting the devices I'm copying to and from... no idea why this card is temperamental, but given the other reviews there is some issue with this media.
Even at its best, I don't see performance worthy of a "Class 10" card. I don't see a discernible performance leap over my slower (but reliable!) Class 4.
