The attachment is a bit fiddly, as it is not good approach comes through the spokes through so, but after 2-3 minutes I had installed the sensor on the rear wheel bombproof. One should make sure short, that he has sufficient clearance and a short turning the wheel flashes a green light and the sensor is activated and ready for use. If you have previously selected speed view in its Vivo Smart so you can see now on the bracelet the speed. I am fully satisfied with the values and the analysis after the ride in the app. The speed is very accurate and showed me on a known track the exact number of kilometers. Gleichtzeitig can also attract the chest strap and therefore has a top evaluation of his training on the bike. Both are coupled via ANT +, which is very stomsparend and barely burdens the battery.
This accessory I can my Vivo Smart now finally use anywhere and not have to get displayed at the end of the day that I would not have moved me, even though I did a 60 day tour KM. The sensor is simply always Fahhrad and every time I get on the bike, the data determined and calculated in my daily balance. I am fully satisfied !!!!
