You can on the device storing up to 4 people and each person gets assigned a number. The device remembers for each Pre-registered person, the values from the previous fairs. So you can not only see how changed the weight, but also how to change muscle and fat percentage. Even one time the weight is then slightly higher, so you can see immediately whether you have put on muscle or fat mass. Especially in the long term, if one changes the diet or completed a Sports Training, I find it very convenient because the weight since even sometimes changed upwards one then but can still recognize the positive effect if z. B. the weight, but also go the muscle upward and thus the calculated caloric requirement at rest (which is, incidentally, also appears). The only drawback: You can not set up in the bathroom, because it does not want to get wet / humid part. But I suppose for the helpful and also very precise values gladly accept.
