I think a good purchase. Encourages movement. It is good to take into account the need for rest ... I can turn off the activity reminder on the device, for example during the rest day, so as not to whine. Battery life is apparently what is reported, several weeks, when used as an activity bracelet alone. What is so amazing + after two weeks of use is the battery life when using GPS, even after a two hour run the battery is less than half full. Brochures and instructions for use mention up to 8 hours !!! Maybe battery life has improved with a small "wake-up" charge. So at the beginning I am really happy with my purchase!
