Finally did, I bought this intelligent balance. I can finally maintain a journal of my actions, day after day, week after week, simply by mounting this unit for several seconds. Configuration is very simple, rapid measurement and the camera looks solid and well finished. The comfort provided by the newspaper online and smartphone really is undeniable: more than entered by hand, complex calculations, tedious tracing curve, here everything is calculated automatically and instantly access complete information (weight, BMI , fat / lean mass variations, historical) and displays them by week, month, year, for a given period ... In short, a range of parameters that make weight followed a good time (well that, it depends the direction of the curve ^^) and we can finally see clearly where we are and take care of yourself effectively.
This is a product I STRONGLY advise to those wishing to accurately monitor their body, or about dieting. It's really exciting to see all the information and changes as clearly.
