"Great"

Yep. Works like it should.

"Great, until it randomly corrupts."

The cars seemed great, but occasionally the card is suddenly "not formatted", even without writing new data to it. Has happened in multiple devices.I lost some video I can't rerecord on it, and am fairly upset.Some forums say that the early runs of these cards did that occasionally and that it has been fixed on new runs, but I find it difficult to trust them now. I have never had this problem with any SanDisk product before, including the 5 of these cards I have in 32GB.Very disappointed.
