Body Composition Scale / Weight Scale This scale measures weight, BMI, and more, and can be linked to a smartphone app. An instruction manual for registering the app is included, although it is in English. It operates on two AAA alkaline batteries. Batteries are not included, so please prepare them. The outer box shows some dents and scratches, but the main unit is like new. Operation has been confirmed. Since it is new and unused, please consider purchasing it!
