回答“My wristband is coming apart at the seam. Will Fitbit replace it?”Yes, they will give you a new device if it is covered under warranty. Fitbit was really kind and gave me a hassle free replacement as my Charge HR's band was bubbling and was coming off. They required me to destroy the old band and mail a photographic evidence of the same, since they didn't have a service station in my home town. try mailing their customer support.
