Poor quality control
This scale works fairly well as a bathroom scale to send weight data to FitBit.<br /><br />The scale is a little frustrating to set up.  It can go smoothly the first time, or it can take an hour for it to stay connected to your phone or to the Wifi network you program in.  After it had been working for several months, mine lost Wifi connectivity and had to be coaxed into reconnecting through a battery replacement, five hours of repeatedly trying to configure it one night, and a couple hours the next morning.<br /><br />As well, there are constant and continuous reports of body fat percentage measurement not working.  The ultimate resolution appears to be getting a replacement from FitBit:  many of the Aria units simply cannot measure body fat percentage.  Extremely poor quality control in that respect.  Even functional units can be finicky about body fat measurement, so you can't tell until you've tried troubleshooting for a while to no resolution.  Support responds largely by blaming the user, but will readily replace the scale eventually.
