I just called amazon to exchange my scale. Hope I didn't make a mistake. When I first got it, i loved it but then 2 weeks later i got different numbers each time i weighed myself. First I was 104. A second later I weighed myself and it showed 118. Then it would change each time I weighed myself to another absurd number. Is it too hard to ask for what I weigh? It's the reason I bought the scale. Hopefully this exchange from amazon will be a non-defected one that can give me an accurate weight reading!!!!
