Review on 512GB High-Speed MicroSD Card for Nintendo Switch, Android Smartphones, Digital Cameras, Tablets, and Drones - Class 10 Memory Card (Gray) by Jonah Koehnke

You definitely get what you pay for. I don't recommend you use this with a switch. Game loading gets corrupted and never completes. Tried to reformat and same problem. Some games load, but games crash mid-game. The card stores data from a PC or phone. But within a day it got messed up and the data was gone. Good for storing files if you don't intend to modify them. If you can get them first without spoilers. Although the adapter works.
