    I got this card to expand the memory on my phone and to have my music and audiobooks on my phone. I have extra space for photos to. The big draw back is that it is advertised as 400GB, but only got 350GB, not even in normal spec variance.

    I needed expanded storage on my Surface Pro 4 since the internal SSD drive was loaded. Just plug this into the slot in the back and the problem is fixed.

    As always, I've not had any problems with this SanDisk Ultra 400GB MicroSDXC UHS-I Memory Card. I purchased 2 of them at a great price for use in Samsung tablets, and am buying another one to use in a Switch.

    I dislike buying a 400gb microsd card and only getting 360gbs. Other than that, this works in my Nintendo Switch.

    I needed a new memory card for my Switch (there are too many good games out there), and this fits the bill perfectly! I bet I can go at least another year before I need to upgrade again!

    I got this on sale and don’t regret it for a second. With the switch needing more memory I know this will provide more than enough and it’s a great brand name card.
