You need a good story when you return it. "Yeah, I don't think this thing is right. It says I'm 120.4 but I'm only 119.5 on my old scale and I know that one is accurate. Maybe it's because this one goes up so high. 250? That's crazy! That's more than TWO of me! Who would anyone even need a scale that goes that high?"  Then stand back so you don't get any butter tears on you.
