I have had it for three years and I only used it for a few months since I can't find its batteries... its body fat measurement was reliable for me but... where will I finally find a battery?

From measurements that are all over the place, you go down, you go up again, and it gives you different measurements again after that. No matter how many times someone went down and up, it showed different measurements each time.

I gave it 2 stars for the good price, elegant appearance, and the number of measurements it offers.
Otherwise, I would not consider it to be of good quality, as it broke after two months and the measurements were showing incorrect values.
It is also difficult to use, as the touch buttons for settings are easily pressed with your feet and you have to wait for it to turn off on its own to start weighing.
The user manual is inadequate, as while you can store settings for 5 different individuals (not children), it is not clear how to select a person to start their weighing in order to display their corresponding fat measurements, etc.
I believe it is unsuitable for use by the elderly and young children. I would not buy it again.

We had the product for 1 year.. good otherwise and accurate in measurements. But!!! One day coming home without anything falling on it as there was nothing to fall, it had turned into thousands of glass shards. And the terrifying thing, beyond the fact that it broke on its own and scattered glass everywhere, is the way the glass became countless tiny sharp pieces. Just think about what would happen to your feet from those glass shards. Caution!!!
