I bought the 32GB x 3 pack. The cards passed the capacity test. The speed test shows that they are theoretically good enough for 4K videos. If you're using it for a Raspberry Pi 3 or 4, you should look for a faster card to avoid slowing down your Pi. See attached photos. Also, I find it "pro" that this doesn't include a full-size SD adapter. I have many. Update: I bought a 3 pack in May 2020, all three are still working great. I bought another set in November 2020 to have on hand. When trying to use them in September 2021, all three cards do not work and are not recognized in my camera or laptop.
