I went to the Fit Bit public forum -uhh ohh- seems like hundreds of people have the same problem
Bought my Fitbit Aria  from Amazon in 2014. It worked really well until I needed to change batteries. That's when the heartaches began. After installing fresh new batteries I stepped on the scale and got the dreaded - step off,- thinking,- ERR. After many many tries to reactivate my Aria, I went to the Fit Bit public forum -uhh ohh- seems like hundreds of people have the same problem. Fit Bit offers no solutions and it sounds like they don't truly have a fix. I am now stuck with a worthless, pretty white brick, sitting in my bathroom. If you want a nice scale that works for ABOUT two years/or until you install new batteries, then go for it, otherwise DON'T BUY.
