This is a body composition scale compatible with smartphone apps. I've used it a few times, but it's been in storage since then. I think it's in good condition. The display may be unstable during measurement. This happens with several units, so it seems to be a specification. If you don't mind this, please consider purchasing. Simply step on the scale and your measurement data is automatically transferred to the dedicated "ECLEAR APP"! This Wi-Fi-enabled "ECLEAR Body Composition Scale" can display weight in 50g increments and, through industry-academia collaboration with the University of Tsukuba, can measure 7 items, including visceral fat level, body fat percentage, and skeletal muscle rate, with greater accuracy.
