I did a lot of research before I decided and I am not disappointed! Including the most important is to know about weighing. This balance is very stable and therefore gives a precise measurement of weight and without that I noticed a margin of error. For the rest, the impedance function is very comprehensive and gives many indications: fat, metabolic age, muscle mass, etc ... The device comes with an explanatory sheet for understanding the results and mark data to establish its monitoring. In conclusion: good purchase for an individual who wants to monitor the precise evolution of its weight! The price is not cheap but I do not regret the purchase.
