The luggage scale basically works without any problems. Only one scale at according to the imaginary function and the correct weight. This is unfortunately not the case. I had packed suitcase 2, the max. Could weigh 23kg. In one of the cases I was, according to the scale at exactly 23kg, with the other on 22,25kg. At the airport but both cases were severe, according to the scale, and by about 1.5kg! I rule out that the airport scale has displayed incorrectly, as it was the case of 2 airports ... Too bad, so the balance is not really recommended.
