As a counter-anecdote I purchased 2 fitbit ultras, and the aria scales and had nothing but trouble with all of them. The fitbit ultra has a design flaw that means that if you wear them in a trouser pocket and then cycle, that they can deal with the twisting flexing motion. This results in popping the plastic case open and exposing the internals (electronics) to the elements, thus rendering them useless in all but fine weather when you're walking. The aria scales have a fundamental design flaw that makes them incompatible with small apartments/flats. They expect to be stored flat, and calibrate over several weigh-ins. If you really have a small apartment, and small bathroom (as nearly everyone in London that I know of does) then you need to store them upright and lay them flat to use them. The effect of that is that they never calibrate and weigh-ins seconds apart where they have been upright in-between can vary by as much as +/- 1.5kg on every weight-in. This makes them absolutely useless as scales... even if the accuracy wasn't there, consistency would have still left us with a predictability that allowed them to have some utility. I tried to `reach out` to Eric (the founder) in addition to the support people about both issues, including reproducible steps to demonstrate the design assumptions that rendered the scales useless. I feel to this day that they released a little tested alpha product and not a finished one. All I got back was an automatic offer to replace with a new one, and later (I was insistent they had a design flaw and clear about the effects of it) an acknowledgement that they were not going to update the firmware of the scales to pre-calibrate each weigh-in (which is what every other electric scale I've ever seen actually does). My investment in every fitbit product turned out to be a waste of my money and time. My investment in time, trying to tell them the issues as someone who cared about them getting it right turned out to be a waste too. I tried the quantified self with fitbit and their version of it failed spectacularly. I now strongly recommend Nike and Withings to everyone who will listen. I should point out I run one of the largest cycling web-sites in the world and this testing was done very publicly, 36,000 cyclists now know not to touch fitbit. I wanted fitbit to win, and that was why I so cockily did tried their range publicly. Nike and Strava (with Android) are the big winners within that community, with a few nods to Jawbone Up. Fitbit was tried by others with similar experience to mine... everyone I know who touched a fitbit has given away, for free, their fitbit hardware. It's worthless to us.
