Something complicated is the creation of body fat analyzer scale. In order not to influence the results, you should weigh only unclothed. This also applies to the first weighing operation. I am personally not one hundred percent behind the body composition monitors. That is pretty much extrapolated and calculated and measured less. The decision as to whether this is the additional cost to the tadelosen Soehnle "Silver Sense" (I have about the landlord about 22, - E paid.) Each must make for themselves.
I can recommend only limited analytical balance.
