    Simply disgraceful, it didn't even last 6 months and not with any daily use. It got stuck in a switch, stayed there, and one day it gave up. It can't even be formatted and with a deep scan to save the files, it showed that it has over 300+gb inside. It reminded me of those Chinese ones that advertised as 1tb but didn't even have 16gb. Waste of money, go for something better. I will provide updates regarding the warranty issue

    Used Google translator because English is not accepted.

    What it should be: a genuine micro SD card.
    The writing speed is at least 30MB/s. Yes, that's 30MB, not 30Mb, like many scammers use to deceive you. The reading speed peaked at over 45MB/s and I have already used it as a temporary backup for some of my 360 video files totaling 234 GB. It still looks nice, without any corrupted files.

    I highly recommend this product!
