Provides rough estimates

In other reviews, it is plentiful and I can confirm it. With several weighing operations at different locations in the bathroom coming back into existence different results that may differ up to 1.5 kg. Especially "funny": if you weigh yourself at the point A, then a completely different place B and then back to A, you will usually receive 3 different results ... When the installation site due to minimal differences in the alignment of the tiles showers etc. plays a role here, I would have expected to occur even same weighing results at least in the same place. But this is not so.

I am considering to send the balance back and try again at another. On the other hand, you will hardly get in this price range a little better what also show the reviews in other products. For further weighings you need obviously calibrated professional equipment from the medical sector, which of course would be much more expensive.
Well, maybe I'll keep the balance yet and arrange me up with the status quo of the estimated delivery.
