Review on 📷 Gigastone 256GB Micro SD Card: Gaming Plus, Nintendo-Switch, 100MB/s, 4K Video, Action Camera, GoPro, Dash Cam by Ron Coleman

I finally installed them to use in my GoPro for ziplining on vacation. When I install them I get an error saying they need to be formatted. They have been formatted. Same error message. They correspond to the information in the manufacturer's specifications. So, no video for me on this trip. Waste of money on camera, accessories, batteries and memory cards as I can't use them.
