If you want to buy this watch for its exercise functions I do not indicate. He is terrible to recognize the exercise, sometimes during exercise he alone disables the function. The most surreal is the calorie count. The other day on a 1H exercise he told that I lost 7kcal, that would be 7000 calories, humanly impossible!
The function of checking heartbeat is also not accurate, always shows beeem above. The oximeter function is the most accurate but still with enough error. Does not have the function of measuring blood pressure. The business card function always disables alone and you have to stay Daily activating again. The step count I can't tell if it's accurate, but it seems that it is, obvious that only if you walk swinging your arm. In terms of aesthetics he is very beautiful.
