This is a digital weight scale purchased on Amazon in 2021. It can also be used as a body composition scale by downloading the dedicated app and linking it, but in our home, we used it simply as a weight scale without linking it. It is a USB-A type rechargeable model. Although it doesn't affect its use, it feels somewhat dull overall, likely due to it being a used item (of course, I will clean it before handing it over).
