DFE Smart Body Scales

This uses 2 x AAA batteries that are NOT included! 

Otherwise it is an excellent and accurate digital scales that also measures (if you go barefoot) your BMI, Fat percentage, water and muscle density, even your water content. The app it links to on your phone is quite decent if a little on the offensive side. (it basically said I was obese)
