A platform of black tempered glass that’s accented by stainless steel foot placements give this bathroom scale a modern, sophisticated look. Instant-on operation provides weight, body fat, body water and muscle mass data at a glance. The scale will automatically recognize you and calculate your body composition based on your weight measurement, a bioelectrical impedance analysis, and personal user profile. (Do not use this scale if you have a pacemaker or use an electronic personal medical device). Requires two CR2032 batteries.
