This is a brand new weight scale that I purchased and it's in the box unopened. So it's brand new in the box. Un opened. It received. great reviews. One review says... " I absolutely love this scale and the app that goes with it!! Also the review says it breaks down your weight into weight from fat, muscle, bone, and water. Works well on both Android and iOS. It also says if you need a simple scale to tell you your weight in pounds without an app, then this isn't for you. This is much much more. Basically if you're smart and working hi tech items, you won't have no problems with this at all.
