The first scale work, however, the batteries ran out always after 2 weeks and at times she forgot the wireless password. On the advice of a friend I have requested from Withings if this was normal and promptly received the offer to exchange the balance. The new scale is run with the same batteries on for months and has never lost the connection. It shows even a cloud icon for the day when rain is predicted. So I have always imagined the future. :) Super portion, worth every penny.
Thanks to the API, there are many applications that can read the data, eg IFTTT, Runkeeper, Jawbone UP or Trend Weight. That'S Fun.
