4 AA batteries (Mignon) are required and last about 12 months.

Hello thesieger The two Aria 2 in white and black are now recorded and available for order in the shop: fitbit Aria 2 (black) and fitbit Aria 2 (white). The release was originally planned for mid-October - but will probably be postponed to early or mid-November. However, no guarantee, unfortunately I don't have any exact information from our supplier yet, but the goods have been ordered.

Well, I don't have any other FitBit accessories for myself, but I can also count with my iPhone in my Fitbit account. My wife has a small Fitbit and of course an account on the scale. Whether it makes sense to see your weight in your FitBit account is something you have to know for yourself.
