I only wore my fit bit now and then, which may account why I am not in better shape. That being said, there is no excuse for a fitbit worn maybe 30-45 days should die on the charger. I get it, the warranty is one year and the fit bit is 18 months. But it is obviously almost brand new. I am disappointed. I had an apple watch and found it too annoying, and promoted Fitbits to everyone. Now, not so sure. My apple watch is 5 years old and still kicking. Maybe I just invest in another apple watch. Not so expensive vs. 5 fitbits.
