    Easy to use, just what I needed. Now I can backup my files, etc. on my laptop so I don't need to worry about losing information. I also will be using to backup my father's computer. I will be recommending this to my sister and brother-in-law.

    This flash drive is excellent, if you need it. However, it is a bit expensive, and it wasn't used correctly by the store. My problem was with the service, not the flash drive. At least now I have one if I need it.

    Small but BIG. I saved all my data in my old computer to this little Flash Drive. However it is only allowed any file that is less than 5GB in size to be copied.

    Bought this to store my movies to watch on my laptop. It worked fine but had to return due to the fact that on my laptop, i have both usb a ports on the same side and when i plugged my USB a logitech adapter if would lag on the mouse and keyboard. So I returned this to get a USB c flash drive. and that worked better for me, but the product it self was good.

    Outstanding value for such a 'high-speed, low-drag' flash drive. And 512 GB - 3.0. There's nothing better out there.
