Buyer Beware, Lots of Recent Complaints
Make sure you read reviews on fitbit.com. There are a number complaints recently (03/2016) about this device not working out of box. Connects to wifi but when measuring weight just reads ERR. Lots and lots, like thousands, of complaints about this. Fitbit.com has no resolution other then remove batteries for 10 seconds and try to reboot. There are zero other options for diagnosis.
