Excerpt: Bought this for my Gopro hero 4 Black. Seems to be working great so far. I did struggle figuring out if I had the right card or not. The picture is totally wrong on the web site. It shows a U1 card. I got the U3 like the add stated so I was only slightly annoyed. It would have been 5 stars if not for the adds picture being confusing.
Excerpt: It may noy be the fastest card on the market, but it probably is the fastest for my camera. Testing has shown that faster backward compatible SD cards would not benefit my camera in terms of speed. Check the rating of your camera before you waste money on a faster card. I use two of these cards in my camera and have yet to fill them in one event. They've been relible and would recommend them.
Pros: Easy To Use, Large Capacity, Reliable Performance, Writes/Reads fast
