RENPHO body fat scale with a black glass surface and metal sensors. It's convenient because it has an official app, making it easy to record measurements by launching the app and using the scale. It charges via micro USB-C, so no batteries are needed. I'm decluttering, so I'm selling it. - Brand: RENPHO - Model: Body Fat Scale - Charging Port: micro USB-C - Design: Black glass surface with metal sensors Thank you for looking.
