The tried and tested Oxygen25 in full working order and excellent condition. It's spent time on my sunny desk, perhaps that's the cause of the antiqued-keys? Either way, you get that awesome vintage look that can't be found on a brand new unit 😉

Connects to a computer via a usb lead (not supplied).

I've used it in Windows and Linux flawlessly and you'll see in the forums there's no problem with Mac either.
