So....I have this Fitbit device I've owned for approximately 2 years which I wear only when exercising which is 4-5 times weekly for an hour. Worked great up until 2 months ago when an issue began with not holding a charge for more than a day. Then the heart rate monitor began to work intermittently. Currently it turns off then back on every several minutes or so resulting in virtually worthless data it might collect as it's incomplete. The device is only warrantied for a year (unless you purchase the extended version) so I'm outa luck there. Fitbit does not offer a repair service on these things which pisses me off. What I'm curious to know is what went wrong....software? hardware? both? Thoughts/ comments?
