The unit is extremely difficult/impossible to setup. I had used the PC based seup on 2 computers and the web based setup on same 2 PC's, iPhone and iPad. None of them worked. I kept on getting a WIFI ERR and it would not connect therefore work. When I stand on the scales, it ends up with an ERR message, so even when not 'WiFi connected', the unit does not work. Very expensive waste of time for me. For those wondering, I am well below the max weight of the scale, so I know the ERR was not because of my weight.
This unit will be going back at the earliest convenience. Thanks but no thanks FitBit.
