I bought this at an electronics store a few years ago. I've confirmed it works, and I'll send it with batteries included! The following is a copy-paste of the product description from the official website: ECLEAR Body Composition Scale (HCS-FS03 series) HCS-FS03 series HCS-FS03WH ¥4,213 (tax included) JAN code: 4549550179720 Features: White This is the "ECLEAR Body Composition Scale," which shows daily changes with a target weight setting function and emoticons. We jointly developed a volumetric estimation method with the University of Tsukuba to calculate body composition data based on MRI measurement data. It is equipped with a target weight setting function and displays the difference from the target after measurement. Weight gain or loss is easily understood with emoticon expressions. Weight can be measured in 100-gram units. It can measure 5 items: weight, BMI, body fat percentage, and basal metabolism.
