beautiful product. aesthetic and easy to use. you learn a lot about its physiology following his weight, muscle mass and hydration status. we are dehydrated after waking up and the balance shows a greater fat mass in the evening. I am "obese" normal waking and before dinner! you can use the tanitaweight application to track its progress (weight loss, dim fat mass and increase muscle recovery after intensive sports!) but create two profiles one for monitoring the morning and the other for monitoring ..même evening if you do not weigh you twice a day !!
