The five functions can be whittled down to three if you remove ‘auto start-stop’ and ‘auto-scan’ from the frame, leaving just speed, distance and odometer as the things that can actually be displayed.
To the Mavic’s credit it displays them well, in chunky seven-bar digits. And apart from mentioning that the magnet will fit bladed spokes, that’s about all there is to say. If you just want an accurate distance measurement to read against your Audax route notes, the MTech 5 is maybe one to consider. In more generic circumstances, when you want to show off your maximum speed from the downhill or determine your average speed, without having to also bring a stopwatch and a calculator, more fully functioned units are available from about £12, which is an extra pound well spent
