As always, perfect delivery amazon, never disappointed by the service. When the scales Beurer BG21, the impedance functions seems correct, stable result of weighing to another. As against the scales only function is pretty far fetched, varition 2kg of 3 successive weighing ... !!! almost never the same weight amount of 2 times on the scale, often an average of 500 g. apart. So moderately satisfied with my purchase, only useful for people who are not looking for a very precise monitoring weight.
