Here more than a month I wear the watch every day, and I remember as positive:
- Polar listening to its user community, enabling integration in November 2014 more advanced features for the daily monitoring (read activity tracker / sleep)
- Polar is for me one of the leaders regarding the monitoring of sporting activities and you have information on the training load on your form
- The possibility of combining sensors that are not necessarily manufactured by Polar. I already had a Polar H7 belt, but for the bike I use a speed / cadence sensor Wahoo Fitness Blue SC compatible with the watch
- GPS accuracy, better than my phone ...
- The battery durability
Regarding areas for improvement:
- Compatibility with Android phones (planned for end 2014) and Google made
- More advanced features in Flow, like that one can find in Strava
- Having more information on future features added in future firmware of the watch (if it exists, I have not found where)
- More details on the tracker function activity (especially sleep, and also the market that is not necessarily detected as soon as you got something, and yes I read while walking ...: p)
In any case, I am perfectly satisfied with my purchase (hence the 5 star) and even more since the last update. I am sure that Polar will surprise us in the coming months with this watch.
