I bought this for my GoPro hero3 Black and it works flawlessly. When capturing in 1080p 60fps it has no problem keeping data and writing. Never had any errors or malfunctions. I've even captured using 4k and had no problems. For the people saying this doesn't work I'm guessing the problem isn't with the card but with either your GoPro or computer.Overall this card works perfectly and is much cheaper on Amazon. Don't bother buying in stores where they will charge you twice as much.
