Very easy, pre-programmed. It took me a while to figure out that it shows the last 6 digits of the MAC address and not the first or whole number. It is in order. It's fun to play with him. Mine has a small bug with the screen (a white bar across it) but it works entirely as advertised. I'd love to see plans to 3D print the cover.
