Worried about reviews, but so far working great
When see reviews for the below, not sure if work or be worth money spent. Unit is old, but last few weeks battery holding charge. Not went a full 7 days, but did 4 days and no issues. Well worth the money to keep my Fitbut Charge 3 a going, instead of cost of a new one. Watched some videos and after some time of being careful getting glue out. To me well worth of having to buy a new unit.LSS271621 Replacement Battery for Fitbit Charge 3 Fitness Activity Tracker FB409 FB410 71mAh
