All sticks appear to be functional, but 3 of them are definitely NOT USB 3.0. I copied and pasted the tests for everyone. Using the same files, 2 of them showed an average speed of around 40MB/s and the remaining 3 - 16MB/s. Just out of curiosity, I copied/pasted the same files onto a USB 2.0 stick and what do I know? Average speed 16 MB/s It is clear that this is false advertising. I will not deal with this seller again.
