very good product easy to use. Contrary to some opinions that the installation in minutes on my Freebox V6 and this via the Fitbit website. Superb product design. The accuracy of the weight is good no gap between 2 separate weighing minutes. Integration into the Fitbit ecosystem is very good. It should actually create accounts for each family member but we have not done for children, They will have plenty of time later to take the lead followed with their weight. I wanted to follow my weight and it's done well and this very simply. Fitbit thank you
