After nearly two weeks of daily use I remain sincerely disappointed.
The bracelet itself is pretty good, all is well signposted but I quickly maperçois small problems!
Already autonomy: 3 days max and yet I synchronize only once a day ....
Furthermore, for the bracelet detects a sporty activitée other than walking and running it is absolutely the belt POLAR H6 so be helmeted 59 or 53 on amazon decathlon.
There is therefore a complete product that but 148!
