Comparing against an authentic SanDisk MicroSD, there are obvious discrepancies in the colors, fonts, shapes, material, stamps, etc. (see photos).
Second red flag was the MUCH lower than advertised read/write speeds (only 50-55 write with mid 80s read).
Third red flag was when I tried to copy data from my old sd card on to this one. I was able to get about 21.5 GB of data on to it until it unmounted itself from my computer. I then physically removed the card and inserted it back in the computer. Windows recommended that I repair the drive, so I did. After that, I go and try to copy the data again and it unmounted itself, just like before. I tried the same thing by repairing the drive, except this time, Windows informs me that it could not be repaired! Seriously??
So much for trying to get a good black Friday deal...
***Update October 21st, 2018***
I ended up installing the microsd in my new Moto Z2 Force Smartphone right after the review, since the weather for flying the drone won't be nice again till next year. It worked awesome in the Moto for over a week until it died and said it became corrupted. I had many photos and videos that were transferred and lost. Called and emailed support and was asked to jump through hoops so am not very happy about the card and experience with it. Will be buying a different brand and hoping for a better ending.
