    I bought this at a great deal for my Nintendo Switch, after wanting to upgrade from a 128gb. I mostly go the digital route for my Switch games and I like not having to worry about running out of space.

    Recently upgraded the memory on my Nintendo Switch and the added 400 GB of memory makes it so you don't have to worry as much about how many games you have downloaded.

    There are often times better deals for these microSDXC's for the same size if not higher, but how fast would those cards be without the power of a blue shell coming at you with lightning speed??

    Always amazed how something so small can do big things. Got this because I ran out of space on my switch. Just plug it in and it was ready to go. Would highly recommend.

    This is the best storage disk for the Nintendo switch. It holds every game you might want to play and makes it possible to download games rather than buying and inserting games discs.

    Just what I was looking for to store all my Nintendo Switch games on. Love the blue color and it has enough space where I don't ever have to worry about inserting another memory card again.

    awesome for my switch but works for many more things! I got one for my switch, but I also bought another to make quick backups of my phone as my computer space is very limited.

    The person I bought this for loves it as they did not realize that the system needed updates until the extra storage was added. Now they have plenty of storage and the system has updated.

    Switch games can take up a lot of storage space if you don't purchase physicals copies. This is a must have companion, especially during the holiday season when tons of games are on sale.

    I think that it is going to be hard for me to fully utilize this memory card. Then again, I rather have to much memory available than not enough.
