The USB sticks worked during the first test. After 1 or 2 uses, the first USB flash drive had trouble loading data and eventually stopped working. If a faulty stick is inserted into the USB stick, you will receive a message: Please insert the disc into the USB stick (E:). I was able to get my money back for this particular flash drive but it still doesn't work. Update 12/14/18: If you use another flash drive after downloading several files and don't use the flash drive for more than a month, the other flash drive failed. and has trouble accessing information. I would recommend that you look elsewhere if you need a reliable USB drive to store your files.
