This is the first generation "Smart Bath Mat" from ISSIN. You can measure your weight just by stepping on it, and easily manage the data with a smartphone app. The main unit, mat, charger, charging cable, and all other accessories are included. The main unit has no noticeable scratches or stains, but the mat has deteriorated accordingly, so please consider it as packing cushioning. This is a used item, so please refrain from purchasing if you are sensitive to such things.
