I operate a commercial whitewater rafting company and we buy these bulk whilst renting out GoPro's and selling the footage along with the card to the customer. We've never had a bunk card or any problems whatsoever over about 40 cards so far. I was advised by my gopro rep to be sure to buy from a name brand &#34;like sandisk&#34;. The adapter is well appreciated by the customer, not only because most people don;t have a port for the micro format, but also because microsd is so ridiculously small that its far too easy to lose.Have and will buy again.
