Pros: Has a lot of storage space.

Cons: Not as fast as other cards I have owned that are lower speeds. Used this for my Samsung Galaxy S3 and it worked for about 2 months. Then started to mount/unmount all the time then no longer recognized. Will not work in any device or computer and cannot format. I have no issue with other cards in any device.

Overall Review: Not sure if this is a problem with Samsung or SanDisk, but either way I have lost all of my photos and videos. Would not buy again.

Pros: Has lots of storage space.

Cons: Not very fast compared to other cards I have owned that have lower speed ratings. I used it in my Samsung Galaxy S3 and after about 2 months it stopped recognizing it, or would mount/unmount repeatedly. Now it is not recognized in any device I try it in or on the computer using an adapter. Not able to format either.

Overall Review: Not sure if this was caused by the phone or the card, but either way I am out of luck on all the pictures and videos I had on the card.
