You can set yourself training targets in Polar Flow and synchronise them with your M400. It guides you through your training and shows you when you should get up and move and when you should rest.

    Excellent. Highly comfortable chest strap and decent Polar flow web portal which shows maps, distances, rest periods, etc.. Well worth it.

    Recently I bought the Polar M400 HR sports watch in red colour. In the PRODUCT DESCRIPTION POLER states that Battery life: approx. 9 hours training time with GPS and sensors. To my surprise, almost 6 hours in my first bike ride, the battery gave up and ruined my day. Never again Polar

    Great for running! Finds the GPS signal relatively quick and is accurate. With the polar flow app you can keep good track of your progress. Good value for your money!

    Eine super Uhr vom ersten Moment an. Einfaches einstellen und personalisieren. Die Funktionen zB Intervalltimer usw sind super. Das gps wird schnell gefunden und ist stabil. Trainingsprogramme selbst erstellen und mit der Uhr im Training abzuspulen. In Verbindung mit PolarFlow, eine tolle Sache. Für den Preis eine super Uhr. Würde sie nicht mehr hergeben. Denn sie ist nicht nur funktionell sondern auch schön.

    Preis- Leistung ist gut. Ausstattung nicht überragend, aber gut. Leicht und wasserdicht. Leider unangenehme Schwankungen bei Lauf-Pace.
