Battery life is good

Worrks great ,but battery life only 4 months

Great item; long battery life.

Pros- waterproof, durable, great battery life, seems accurate enough for tracking, app seems great at long-term tracking, customization is easyCons- syncing problems make it unreliable and therefore useless for my purposes

battery life is so much better than having to charge the device all the time.

I think it's accurate, and it is easy to sync with my mobile devises as well as by home computer.
