[This review was collected as part of a promotion.] I love this memory card.It doesn't lag or freeze up like most others I have used and it doesn't keep telling me to format my memory card until everything i had on it is lost.I use it for a backup for my home security camera I can record hours on this memory card 256g holds alot of memory.its not built cheap it is reliable.i would recommend this micro to anyone it has great compatibility and stands on its durability.

[This review was collected as part of a promotion.] The T9 is a perfect match for my Nintendo Switch. With more than enough MB for me it stores all of my favorite games. I'm impressed by the T9 micro for the speed, I love that they load instantly without having to wait, which means more time to game! It's durable and reliable and I highly recommend samsung products as a whole for everyone's technology needs. Thank you Samsung JOB WELL DONE!!
