I chose the wire for its reliability and simplicity of the system that does not require additional batteries in contrast to a wireless. The meter itself is perfect once the user manual integrated, Sigma's official website is very clear for those who have concerns, videos and interactive displays are available for this model, everything is clearly explained. Question ergonomics, it is attached and removed in a quarter-turn, it fits perfectly well even when it shakes, it is waterproof in the rain. Visible even in the sun; this model allows the adjustment of intensity 3 position for the LCD. 4 buttons to navigate through the different modes. A little gadget functions such as calculating fuel savings if we had made the same journey by car, or a thermometer not necessarily essential. It can recover data to zero per one or reset all data (except with regard to the total trip disantce and the total time traveled with the meter) thanks to a long press on the latest top left button.
