Having seen several models, in terms of aesthetics and quality, Sigma seems well above average in the same price range !!
With 150km counter so a beginning of use, I am very satisfied. The performances turn out to be real. Starting in the second round wheel accuracy in the speed display, very responsive ..
I bought two, as I ride regularly with a friend. Each his own, then, at the end of a 40km ride, knowing that one is more or less the same runs we arrive with gaps 200 / 500m. Average speed 0.3 / 0.5 km / h difference. When driving coast to coast are shown exactly the same speed. For settings I have measured the circumference of my wheel (because I not find my reference in the instructions), my buddy the price value corresponding to the ref. its wheel on the manual ... NO PROBLEM NO INTERFERENCE BETWEEN OUR TWO OF METERS !!!!!
Not yet used in deep mud, but well-stocked forest ... We put the transmitter behind the fork to avoid clashes with branches or other truck lurking.
Good stuff, to buy without worry ...
It remains to see the autonomy of the brothel in the long term ... Announced 365D with an hour of daily use, or 7am ATV week !!! Gone guys on bicycles.
