This product is just not fit for purpose and considering the high price is a joke! It is excellent product when it works and real shame it doesn't happen so often. Even when the watch is stable, a dodgy software update makes the watch not functioning. (clearly not adequately tested before release - fortunate they don't deal with safety critical applications apart from someone's heart rate exploding) . Some of the faults I have experienced to date1. Wristband heart rate monitor didn't work when received as new. Had to reset it several times to persuade them to repair. Took some time to turn around - not good customer service.2. Issues with unreliable heart rate with wrist and chest bands. Some time reporting over 250bpm which is a big concern on the accuracy when you push your self. 3. Not picking up GPS4. Heart rate function comes and goes depending on software release.4. Recently when you press button to start activity, it does nothing even though button respond wen used for other functions.It's time I don't put up as a consumer with this rubbish. Next time I give a chance to another company.
