This product is helping me track my progress on my 2021 get fit program. It gives data I had no idea could be derived from stepping on a scale. Only gripe is I cannot change the scale reading from kilograms to pounds. The manual does not explain much beyond the basics. I have no clue where to find instructions to make the adjustment to the device's units of measure. Again, it's a pretty good scale for fitness. Just could be a bit better by being matched to a non-scientific consumer who is not as familiar with the metric system.
