S.H.
Every Scale is different.
We have the Wii board/scale too.
We also have a digital scale.
KEEP in mind, that if a scale is on a carpet... this affects its read out.
Or if it is on a hard floor, it will affect the read out too.
And everyday, when a person weighs themselves, they are wearing different clothing or it is a different time of day etc.
Or for women, water retention etc.
It all affects daily weight fluctuations.
Just choose a scale you want to go by.
And use that one.
