After warrantee expired (1 yr and 2 months) the connector on the tracker totally broke off. No longer able to attach it to my wrist. Only offer was 35% off another purchase of equal or lesser series. The tracker works fine. I am trying gorilla glue to re-attach it. So far so good but I sure this is temporary. No more fitbit products for me. I will try another tracker from another company and see how that goes if I have to get another.
