Thank you for viewing. This is a RENPHO smart body composition scale. You can check detailed information about your body, such as BMI and body fat percentage, using the dedicated app. It's a high-end model that supports both Wi-Fi and Bluetooth. With Wi-Fi connection, data is automatically recorded without having to launch the app every time, which is convenient. I previously purchased it from Amazon Outlet, but I ended up not using it because I received another body composition scale from a relative around the same time. It's unused, but the box is damaged due to it being an outlet item. The accessories are all shown in the photos. Thank you. ■ Smartphone connectivity, achieving ultimate accuracy with ITO coating technology. ■ LCD display of weight, body fat percentage/BMI. ■ By simply stepping on it, 13 health metrics can be measured.
