The SmartWatch function works well. The Activity Tracker is a nice gimmick. The GPS signal is found compared to all predecessors Garmnin much faster. The position is located in approximately 10 seconds. The bike sensors, the heart rate monitor and the connection to the mobile phone is quick and reliable. The comfort is good and altagstauglich. What I still lack :? Zoom in the Map mode, manual height adjustment, transmitting positional data and routes from Base Camp at the clock, and pulse rate measurement even when swimming. Anyone who does not need all the new gimmicks with the 910 also a faithful companion for almost any sports activity and less for about 150.
