DID NOT WORK

Did not work; will not lock when USB removed from computer. Attempted multiple USBs and different settings. Save your nickels.

Not Secure

The password on usb is only 37 characters long. Plus there isn’t very many customization options

works

it works but i wish it had more customisation options. also the “eject on sleep” mode is useless because when it locks the screen it doesnt automatically sleep

Nice

Turns my old USB stick into a key. I'd like to see a few more features. It would be nice if it could stop my music when i yank out the disk.
