MOUTIL 400GB Micro SD SDXC High Speed Class 10 Transfer Speeds Action Cameras, Phones, Tablets PCs

This card is just barely working in my Surface pro. Super slow transfers that just stop. Not sure what gives but seems to be bad!Edit - Just to fill you in I returned this item, thanks Amazon. I had emailed the seller to no response. Surface pro 6 doesn't like this card at all and its incredibly slow. Tried a new, different card and it worked like a charm so yea- avoid this

Bought this for my Surface Pro. It formatted quickly and seemed to function fine until I started trying to install software on it. It performs so slow that may applications just timed out. Piece of junk.

Either it cheap or a fake. Cannot use more than 64GB of space on it.

I put this 400 GB sd card into my 8" kindle to watch youtube and movies on it. Those are memory intensive. The price made it affordable. The other well-known brand cost nore than my kindle.

Every time I send things/files to this SD card.... they disappear!!!Having the worst time with this!

I used it in my smartphone. Most apps will not be detected if transfered to the sd card. Can only be used for simple files like pictures or mp3 files.

would not store my files

This SD is very good for a Samsung galaxy s9 plus coz have 400g and after been formatted till keep 400g thanks guys I'm happy a lot for'.
