I could test it for running, cycling, walking and gymnastics.
It happened sometimes that GPS is a little slow to start, but in 90% of cases it worked perfectly.
So we can schedule sports sessions, and then follow in real time on the clock (current and average speed, pace, heart rate, calories, time remaining, course design, etc ...)
Then at home, the wireless network does the rest, one can find the results directly on the dedicated online portal.
The training plan is really useful for those who want to do a specific session as: 10min warm, 4 acceleration 100m, 25 minutes at increasing speed, return to calm, etc ...); and follow his routes and because there is the route of the path on the GPS watch (which allowed me to not lose myself trying a new route!).
Planning can be done through the portal on the internet, or with the dedicated Android application.
You can connect a range of ANT + sensors (heart rate monitor Decathlon works fine, for against the speed sensor and cadence is not yet developed)
The battery is correct, you can adjust the frequency of data to save the battery, anyway unless an extreme sport to make workouts more than 5/6 hours, the battery is sufficient.
The dedicated portal is functional but incomplete: it shows statistics of all drives, paths, tower detail, etc ...
I preferred transfer data to another site (such as RunKeeper, for example) in order to centralize all my training (swimming, etc ...) with the gpx files easily exportable.
There a few months, the community looked very dynamic air, and Motorola seemed to listen to the suggestions of its customers, but it seems that for some time, it is asleep, suggesting the release of a new then model or discontinuation of the product?
With its new lowered price, this watch is still a great product and now affordable way to consolidate MP3 player heart rate monitor, GPS in a small very friendly product design.
