    I got this for convenience as a simple alternative to my regular external drive. However, it's way better than expected. The flash drive has a lot of space for being so tiny, it can be encrypted, and it easily moves back and forth between my desktop, laptop and my iPad. It's my main flash drive now!

    I was looking to make a bootable USB and came across this gem, took no time to set up, now I have a bootable linux USB that works on USB A & USB C for under $30. Took more time setting my bios than it did to get this working

    A perfectly small in footprint, but large in storage drive that allowed me to carry it on backpacking & rafting adventures so that I could download photos & videos easily from my phone. A real winner!

    My favorite type of thumb drive. Includes both USB-A and USB-C. You’re able to flip the drive around to use either of the connectors in either side. Works exactly as intended.

    For the price of $33 for 256GB of storage. The USB A and USB C transfer speed is great. I can use this to connect to my phone via USB C to transfer files. The only downside is the flash drive gets hot quickly (even after a couple of minutes).
