I have this balance now about 1 year and had the following experience: - Sometimes you have to be very long and the "pillar of salt" are frozen on the device, only a Ergebnis.Für elderly or people with mild balance problems is absolutely inappropriate. - If the weight announced and immediately afterwards comes "goodbye" then the measured weight is wrong under warranty. If, however, a break after the announcement and the weight scale then switches off (so about 10 seconds) is the weight mostly correct. - I have in quick succession my weight checked several times on the scale and had differences of about 10 kilos, in my view, also due to the long "waiting time" in the announcement - The measured weight is not stored in the display for a few seconds after being shut out of the balance, so man could shorten the long wait for the announcement .. - After the balance has continuously told "bullshit" I changed the batteries after the unit functioned properly two weeks, the weight was announced quite rapidly - since yesterday again the old problem, one imagines it - and waits ... and wartet..und waits until at some point a "estimate" will be announced. Nowadays, people can go to the moon, atoms split, the heart, lungs, etc. transplanted, computers become more powerful, but the producers are not going to build a simple product such as a properly functioning scale able.
