I have used the memory card into a S4mini to store photos, videos, music, documents and data backups and unfortunately had a lot of data loss complain. 30 photos were actually only 3 read, the rest had JPEG data errors. Other documents could z. T. also no longer be read. That it can not be on the device became apparent after replacing the card.
After the paper values this card should be top, in fact, I had particular the above problems that ultimately led me to return the card.
However, I can not rule out that I am a victim of SD card fakes. As is known, yes for some card counterfeit replicas in circulation, may in this case also.
Nevertheless, I see the result, no reasons to give more than one point. Other buyers I can only give the advice to observe abnormalities accurately and possibly to replace the card.
