Wow! Fast memory card. I bought this for my new GoPro Hero 3. Great performance for full HD video.Shipping was fast, and nice communication on shipping and estimated arrival time.The SD Card adaptor works perfect in my full sized SD reader built in my laptop.Transfer speeds were blazing and read speeds are amazing.SanDisk is the best, really worth buy the top end class 10 micro SD card.If you doing HD video this is the card for you. Video is demanding, so youneed a SD Card that can keep up.In Hawaii we play hard, and the GoPro and SanDisk card have been working flawless at full 1080p60 video.
