This is a nice digital scale for weight. And the body fat reading are somewhat useful, if you don't take them too seriously. The manual gives you no guidance whether to enter yourself as 'male/female' or 'male/female athlete'. By going to the web site, you can get a hazy description of the difference, and make your best guess. In practice, for me, selecting 'male athlete' will give a body fat reading half that of 'male'. So, you really have no idea what your actual body fat % is, but using the same measure over time can tell you if the % is increasing or decreasing.I ended up using 'male', not 'athlete', since that number corresponded most closely with a recent figure computed by my doctor, using a hand held monitor from another manufacturer. But, without that guidance, I'd have no idea what the is real number. So, this is a good scale, with a FWIW body fat monitoring bell-and-whistle.
