tried on different floors the scale. Tiles, parquet, carpet. At each weighing the scales showed a different result. Between 78 and 83 kg. In most cases, no clear result was observed because the weight permanently changed on the display, until the display ausschaltete, although I have been very quiet on it.
A note to the forwarding: What you pay for actually 50 euros for Prime when then a parcel service (UPS) is tasked needs 3 days for the delivery?
