Does anyone have any experience with these type of scales and do they really do what it says they do? It would be pretty cool if it could really do all that. Expecially water weight since that changes every day.

I have this type of scale. Works great. My weight & is always the same as doc ofc. I don't pay attention to water weight. O wouldn't mind a fit bit scale that automatically updates your info. That'd be cool.
