Review on 📷 SanDisk 64GB Micro SDXC Extreme Memory Card (2-Pack) SDSQXA2-064G-GN6MN with GoPro Hero 7 Black/Silver/White Compatibility - UHS-1 U3 A2 Bundle + Everything But Stromboli Micro Card Reader by Jason Melvin

The authenticity of the SD cards has yet to be verified. The color of the packaging and the card itself differs slightly from well-known original cards ordered from the manufacturer. It can just be a different batch or a different supplier. My problem with the cards is that the transmission speed is lower than stated. The card reader/adapter is another real performance bottleneck. It looks like it will transfer files at a speed similar to USB 1.1. Performance seems better if you use a different card reader or adapter. The USB adapter I received stopped working after a few days. The capacity of the hard disks corresponds to the declared one.
