An excellent value fast card that works with my son’s NINTENDO Switch 2. Pre-formatted, this is very good value.

G Ling –
It works, large capacity and quick transfer. Bought for Switch 2. No problems so far although seems expensive for such a small thing.
Scott Phillips –
Needed an express microsd for my nintendo switch 2. There wasn’t much choice at the time of purchase so this was a good deal and has not let me down yet. Games stored on the card run just as they do off the internal storage. It was easy to set up, just plug in to the switch 2 and start downloading
