Unreliable. It's at most a toy, a Tamagotchi.
This item is much more of a toy or Tamagotchi than a &#34;fitness scale&#34;.  Accuracy was non-existent, UX sucks, and support was poor.  If you want quality you'll probably need to wait a couple years for Fitbit to get its act together.  Sadly it took several hours to discover my Aria was a lemon ( http://en.wikipedia.org/wiki/Lemon_law ), and we had to discover this fact the hard way since Fitbit's support is slow and 20th-century.  More on what went wrong:<br /><br /> * Body Fat feature is purely a toy: The scale's body fat measurement suddenly dropped from 30% to 15% without me changing anything on the scale or in the app.  Moreover, day-to-day measurements appeared *inconsistent* with my food intake-- my body fat has trended /down/ over a week of eating /more/ fatty foods (and carefully maintaining constant water intake).  And what the hell is Normal vs Lean mode?  Is clicking Lean supposed to make me feel better about myself?<br /><br /> * The scale's measured weight was more than 5% inconsistent between weighings (even after 5 weighings).  After drinking a bunch of water, a Shaper Image scale confirmed I gained 2-3 pounds and yet Aria registered no change.<br /><br /> * The wifi setup is A MAJOR PAIN, especially when the device FAILS TO CONNECT to your wifi.  I lost over an hour trying to get this thing to connect to my standard 802.11 WEP-protected network.  Laptops, phones, iPads, and lots of other devices have no trouble connecting.  There are SO MANY THINGS wrong with Aria's UX, from requiring you to enter your Fitbit login and scale name on EACH SETUP ATTEMPT, to using (on mobile) an out-of-app web flow, to the web app not reporting the same errors as the scale itself. Fitbit's Product Managers need to take a hard look at how Chromecast does buttonless wifi setup, which is orders of magnitude easier and ACTUALLY WORKS.  They could also spend a couple dollars to put a Bluetooth chip in the scale for not just setup but sync.<br /><br /> * Fitbit wouldn't issue me a straight-up refund.  In comparison, Amazon gave me a refund for an unopened Fitbit charge that I returned to them *without a receipt*.  Furthermore, Hoka One One (a new shoe company) gave me a FULL REFUND for a WORN pair of shoes that failed while I was running.<br /><br /> * While I guess I should be happy Fitbit even answers email, their email support isn't much more than somebody walking you through a bunch of troubleshooting wizard questions.  I asked to actually converse with an expert several times and was denied.  While the people answering emails appear to be doing their job well, the managers who set up this whole process have done a pretty sloppy job and let down their own staff.<br /><br />Unless you're a gadget freak and really want a toy regardless of its reliability, get yourself one of the other scales on Amazon for a fraction of the price.
