This Futrex machine is 99.9% accurate and it tells you how much fat you could have by Percentage or by weight. It also tells you how much muscle you could have in the same manner and also tells you your body water which is key for health. This machine used to be initially bought for $5,000 and I am willing to let it go very discounted as I have 3 of them. Also, I just got it back from sending it into Futrex they usually told me that they did a couple of adjustments and now it is as good as new. You’ll call Futrex if you want and they will back me up.
