    Picked up this large memory card on sale during black Friday sale. One of the biggest memory cards out in the market right now. I'm currently using it for my samsung note 9 phone. It has plenty of storage so stop reading this and buy one now!

    I bought this SD card to use in a Nintendo Switch. It works great and have had no issues. Just be wary about buying inexpensive cards from other merchants promising high capacity as the storage may be spoofed. I chose best buy because I do not have to question the legitimacy of their products.

    I purchased this card for my Nintendo Switch and it works as it should. You have to install an update to get the Switch to read it but after that I've had no issues installing games on it. Would buy again and I recommend it for anyone looking for memory for their Switch.

    Always been wandering how, in heavens name, such enormous amount of digital data can be packed in a miniature rectangle? Here it is - SanDisk micro memory card! Moreover, lately they have come up with a 1 T card. Unbelievable! What comes next?

    The storage on this is fantastic. I'm a Nintendo switch fanatic and I have many many games installed because of this. In terms of PC transfer speeds it's standard fast for budget sized cards So you won't be wowed there. It gets the job done.

    I upgrade these on my phone pretty often, my music library grows pretty frequently. That said, these come down in price pretty quickly it seems, so if you hold out long enough, you can get an even better one at a comparable price.

    Recently upgraded my Switch from a 128gb card (also a Sandisk) to this 400gb card. At the prices they're going for these days, might grab one for my Surface Pro shortly too.

    This was a bump in data for my Switch, so now I’m set for future releases on the system! The save-transferring process sucked, but that was on Nintendo; the card is great!
