Bought for my wife for professional running. The wife is delighted. Very comfortable to wear, lightweight and practical. There is gps, when running it shows the distance traveled. Heart rate monitor, the volume of oxygen in the blood (although it is not clear how it counts, but it grows a little with each workout). When starting a workout, you can choose a convenient display format, for example, to show the distance traveled, time and heart rate. There is a watch app. There, after training, you can see on the map the distance traveled, the height difference. Also, the clock is attached to social networks and vibrates when messages arrive or call. I recommend to buy.
