A month after purchase it stopped working on any of my devices! Originally used for Android phones and just stopped working. Try it on 4 different devices (2 Android phones, laptop, tablet) and none of them could read it! Very disappointed with the product but too late to return it!

Purchased for Garmin GPS...this is a medium sized memory card and is needed for extra storage when backing up the annual map update. Aside from figuring out how to put the card in the slot, it seems to do the trick. It got to the point, so I recommend it.

This card says it can read up to 70MB/s. I haven't tested it, but when copying files, the maximum speed was 20 MB/s. GoPro reported the SD ERR error quite a long time before the card completely failed. Now I know people will say it's not fast enough for a GoPro, but a true Class 10 U1 Micro SD card shouldn't bend when capturing a 1080p@24FPS file. It's cheap for a reason. This is not a quality card.
