Phenomenal product!!

This is, by far, the best and most reliable micro SD I have ever used. Reliable doesn't even come close! I cannot get into too many details but I can say that any other card would have failed 10 times over but this one stood up to the perils and pulled thru without so much as a lost byte. From the looks of the card, it was toast, all info lost, but once I cleaned it up and plugged it in, boom... Nothing lost, nothing compromised. So I bought 3 more. Thank you a ton!

Excellent for Switch 2

[This review was collected as part of a promotion.] This card is amazing for my switch 2. I used a different brand when I first bought it and it stopped working within weeks. Ordered this one and will never order a different brand again. It's lasted the whole year I've had the switch 2 and hasn't lost speed. Games load in a snap. I wish I'd gotten the 512gb but probably will soon to keep toiling at the back log.
I would recommend this to a friend!

[This review was collected as part of a promotion.] It work on my switch 2 have and it did transfer my switch games to my switch 2 and it was quick to transfer the games from my main storage to my express microsd card. The reiliability i ok but was not reading my games on the switch 2 that i have on the express microsd card 30 seconds later it was show my games the capacity hold most of my switch 2 games that were too big of a storage to hold it on my main storage i didn't need a repair on the express mircosd card the durability might not need to be repair cause the express microSD card was perfect but too easy to get loss and cost more money to get a new one and have to get the games back by a different account that don't have the game
