There are not many models of GPS heart rate monitors, and the appearance is relatively fashionable, and it is not exaggerated for daily wear. The weather and call functions after Bluetooth connection are practical, and the GPS performance is also very good in terms of star search speed and accuracy, and can be smoothly connected with other brands of ANT heart rate belts, which has strong ease of operation. However, due to the fact that the product has just entered the mainland market, the durability has not yet been verified.
