Works even with older Logitech mice that didn't originally come with a pairing dongle. To install, download the Unifying software from the official Logi website. It's an orange badge, the same as the one on the key itself. Install the app. Run the setup wizard to pair your new device and you're done. I added 3 devices to one key as soon as I got it.
