To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This scale is well built and the app is full of features. It also takes weights accurately. But it's body composition reading is completely inaccurate. I realised this recently after I ordered a second unit for a friend. He is slightly overweight, and has visible flab in his upset and lower body, yet the machine reads his body fat at 12.5%!! Use it as a weighing machine, but don't depend on its reading for body composition.
