Query: Tanita BF680W Duo Scale Plus Body Fat Monitor with Athletic Mode and Body Water

This unit replaces a previous Tanita scale we had used for nearly a dozen years...it just wore out! This model has easier to read numerals and has faster processing of information. I like the "Body Water" feature. However, this is more of a novelty to me because I an not really into athletics that much. Would have given the unit '5 Stars' if it were not for the smaller 'foot print' of the overall unit as well as the much smaller heal/toe pads being further apart. My wife has a very small foot and she finds it a little difficult to make what she would hope to be "full contact" with the two pads for each foot. We plan to wear this one out too!!!
