Review on 512GB High Speed Class 10 Micro SD Card with Adapter - Top-Notch TF Card for Ample Storage by Amrozi Goodall

Attention buyers. DO NOT BUY THIS PRODUCT! I bought this 512GB for only $23.70 thinking I got a good deal because I need a micro SD card for one of my phones. 1.) The writing speed is very slow and 2.) When I was copying files from a backup source on my computer to the card, put the card into the phone, turned on the phone, suddenly the files mysteriously disappear. Buy cheap, get cheap. Trust me, you're better off spending the extra money and using a well-known brand micro SD card. If I could give zero stars I would.
