Although it is not really very beautiful (it is even less pretty true), I immediately studied the manual. This balance, however, is simple enough to use must still read the manual to find out the procedure for the complete measurement.
The more difficult it is well positioned and well hold the handle at the right place for the measurement to be reliable, without moving!
One can have four user profiles. The profile is easily created with its sex, weight, age, height. After each complete measurement can be seen its previous measurements to compare.
Besides its weight can also see your BMI, body fat percentage, skeletal muscle, visceral fat level and metabolism at rest (in calories). The manual is very well done as it explains well what are the measures and what they correspond. It also explains how to analyze the results.
... My only problem is that 3 users, for 3 consecutive days, we all had mixed results. Not by much but still ... I even made two measures 5 minutes dintervalle and weight of 400 g was different ... so my BMI was also changed. I have not moved yet the balance, it is the place I put my battery or other scale (the most stable area of the house). These are not huge changes but it's still a bit limited level accuracy.
I'll see in a month what happens. I like anyway because it gives a good idea of work to do;)
