    The drive was convenient since not all my devices are usb-c but a few. Most of my devices are still Usb so this is a good in-between

    Small enough to keep on your keychain. Don't be fooled into thinking you need to install SanDisk software on your phone or device. Built-in software can detect files on this drive easily enough.

    I have a macbook pro, which unfortunately only has usb-c ports, but this makes it so much easier to use. No need for an adapter and works just perfectly fine. Would definitely recommend if you have a device with a usb-c slot
