The Mi Smart Scale 2 uses advanced technology with a series of complex algorithms and Bioelectrical Impedance Analysis to produce accurate statistics. This scale can be used to weigh people, packages and groceries, calculate BMI and body type and test balance. This scale has the ability to identify specific users and can store up to 16 user profiles. The elegant design hides the display until you step onto the scale. After this, the reading is delivered using LED lights.
