Good luck! Just off the phone with them. Be glad that you got the 2 year warrranty - mine was a year -- had to replace it because it stopped working and they could not fix it. Less than a year that they replaced it, I too, am getting those lines. Reset again, no change - too bad - over warranty - even though they replaced it less than a year ago. I ask how long should they last - guy says 7 - 10 years. Yet I guess you and me got the only 3 that don't last. Offer was 25% off a new fitbit. I am close to 60 years old, I do not abuse my fitbit - it sits on my arm - it does not get dropped or wet - but can't last more than 9 months - I say ask for an upgrade since this version does not last very long.
