I just no longer need it as I have another scale and mainly use our wii fit. Nothing wrong with it but for some reason I could never get the water reading to work for me. Everyone else that tried it (I had several people try it) it worked for them every single time. I'm not sure why it wouldn't work for me I guess I stay dehydrated or something I don't know. Anyways $50 OBO. It retails for $100 plus shipping.
