good watch for the GPS running. I use 1 to 2 times a week and it gives me full satisfaction. It takes quite well the load (several weeks) and recharges very quickly. I can sync my data using the dedicated application and check the details of my outlets on the Polar portal. By cons is true that here is not the most practical: turn on the PC, plug the watch, start synchronization, connect to the web portal and view its outputs ... I am very happy anyway
