The neat head unit looks really classy and the speed sensor, considering the size of battery it houses, is surprisingly neat. Set-up of both components requires just a couple of zip ties each, and the head unit mount gives both bars and stem options.

On the move, speed and distance were accurately conveyed without any aberrant spikes, troughs or loss of signal. Display size of the two-data field was clear with the larger current speed figure especially so.
