    I bought this to move many of my files from Windows 7 desktop to Windows 10 laptop. Although it didn't state that it was compatible with Windows 10, a Best Buy employee assured me it would be fine. Happy to say it worked out great. I copied my entire iTunes library. It would probably have stored all my files on it to transfer if I needed that.

    Great price for decent capacity on this flash drive. I ordered online and it was ready for curbside within the hour. Held over 400 large megapixel photos plus documents. I like the slide feature of this USB as well and I would definitely but this again.

    This is a great little thumb drive. Priced well with adequate body strength, and includes a neat, though tiny labeling space. Great Western Digital San Disk quality as well.
