But if you only want to replace the band you can check the retailers/Fitbit and see if they have any left in stock.
They stopped making the Fitbit charge 2
A:AnswerNo unfortunately the Charge 2 bands do not fit the Charge 3 or vis versa. There are so many offbrand ones you can buy online that work great and they come in a variety of colors and designs.
A:AnswerIt's the whole product, everything you need plus instructions and references to the web site... The size refers to the band. At my Best Buy they have a display for size comparisons.
A:AnswerJust attache to the charging station which I have plugged into the same multi-port as my iphone and ipad chargers. Usually charge while sleeping so I do not loose tracking of steps,etc during the day.
