The device is of the electronics forth easy to use, but what the measurement As bad: First, the imaging how and where you have to measure is totally incomprehensible. Really just a line on a poorly subscribed arm. About YouTube but I could then find out. OK.
But to measure the upper arm, it is when measured alone, only possible to create the skin fold with the device. If you do not have quite a bit of fat at this point, then that is hardly feasible, because muscles are not wobbly enough. And I am now physically totally average with a BMI of 24, then tweaks it for a long time with the device and it does not constitute a measurement, because the pressure is wrong, only one is not stated whether it is too high or too low.
At the abdomen measurement is simple but reproducible values I have not yet received (fluctuated 23-30% within 3 measurements).
I would not recommend this unit so.
