Got this to expand storage on my Nintendo Switch and so far so good. Great speed and reliability, which is what you expect from SanDisk. Comes with normal size SD adapter if you need to transfer files to a Mac/computer.
UPDATE 21/6/19: I had initially purchased the 128GB version of this card for my Nintendo Switch, but having run out of space for games I decided to give this one a go at 400GB. It works flawlessly as the previous card did, so now I have a lot more room for games. The price of the card has come down, so the 400GB is the best value per GB.
