If you have a gopro, get a different card, it worked in mine for a while then stopped, turns out the gopro fried it, no fault of gopro but through sandisks error, sandisk will replace it but it can get fried again. I've read up on it and it's a common issue, so if you use this for a gopro, get a samsung or patriot or something else to be on the safe side.
