1. Two weight units: LB and KG. you may convert freely by pressing the button on the back of the weighing scales for people
4. Friendly design: round edge and corner are safe are safe to you, tempered glass is sturdy to step on, sleek surface is easy to clean it
3. Non-calibration before weighing: our scales was calibrated twice before they're packed, you needn't calibrate weight again. If the bath scale is on hard floor, and value in the display screen will be real weight
5. Maximum weight: 400LB/180KG/Minimum weight: 0.2KG(0.44LB): if weight is between it, we're sure it's accurate; beyond it, we recommend you to use other suitable scale
2. Auto power activation and deactivation: stepping onto the body weight scale triggers the sensors to start up instantly; stepping off the digital bathroom scale will cause it to shut down.
