This is a pretty good product for keeping track of your weight loss (or gain). It is not super accurate though, but still gives you an idea of whats going on. I had my body composition done professionally. I checked it against the scale and found that if I entered myself as a male, it was very accurate (I'm female). I believe this is because it doesn't account for athletic body types.Get more detail about Omron Full Body Composition Monitor with Scale.
