Review on 💾 High-Speed Silicon Power 512GB Micro SD Card U3 - Compatible with Nintendo Switch, SDXC microSDXC Memory Card with Adapter by Patricia Wilson

The best way to authenticate a MicroSD card (or any other type) is to refill it and use it when its capacity exceeds 50%. . This card works fine, as does my 256GB silicon power card. "Too Cheap To Be Real" cards are low capacity cards that lie about being huge, so filling them up will reveal the lie. Both of my Silicon Power cards are genuine.
