I have used all 3 different belts for different purposes. Wrist for running, arm for swimming and chest for HIIT and martial arts. It doesn't track properly and tells you your heart rate is lower than what's actually being recorded on other devices. Stops recording when heart rate increases too quickly and turns off at a random time. waste of money.
