The measured values of these scales are very stable and accurate. I have compared them with two other cheaper scales. The deviation was constant and was between 200 and 300g. What I liked very well, was the accuracy of the fat measurement. On the advantages and disadvantages of the BIA measurement I do not want to tackle here. Suffice it to say that the Withings scale has always recorded the same changes as a different scale with handpiece. This fact made me pleasantly surprised, the final is only directed at such a balance of power between the legs and behind the torso aside.
What has, however, I needed in the scale, were more relevant body measurement data, such as muscle mass or Visceralfett. The additional features such as air quality measurement or pulse measurement I found rather superfluous. A handpiece for a more accurate measurement would also be fitted with a scale in this price segment. There's a star deduction.
