I didn't try any command line utilities and only use it for the web with Firefox (e.g. GitHub). Can confirm: Works well on both Linux (needs some udev rule, but I think that's true for all these sticks?) and Windows.

To further answer GP: Lacks Bluetooth/NFC, so it's not usable with a smartphone (okay, maybe with a large USB-OTG adapter). No idea on the supported protocols, I think Yubikeys offer a lot more options there, but it's good enough for web authentication.

Manufacturer support was pretty good: My first token was DOA, and I got a replacement token plus a free Mini. The replacement is now my backup unit and, as mentioned, carry the Mini on my keychain.
