Thank you for viewing. I purchased this about six months ago, but I am selling it due to a move. Please refer to the official product page below. https://asken-shop.com/view/item/000000000001 This is an Asken original body composition scale that can measure 13 body composition data points. It links with the meal management app "Asken," and you can easily record your weight in the "Asken" app just by stepping on the scale, making it easy to continue managing your weight without any hassle. *You can purchase up to 3 units per order. *Please update the "Asken" app to the latest version before use. Thank you for your consideration.
