Works perfectly, simpler setup
I purchased the Aria about 6 weeks ago.  As others have mentioned, it is a beautiful unit.  I have found it easy to use and motivating.<br /><br />There are lots of excellent reviews on here already.  I just wanted to add that I believe Fitbit has simplified setup since the 2012 debut.  I found it very simple to setup.  I put it in setup mode as directed, it found my network, and that was it.  Works perfectly.<br /><br />I have found it to be pretty accurate.  A few times I have noticed a sudden jump up of my weight from one day to the next, but when I have stepped on it again it came back to within an expected range of my previous weight.  The day to day measurements are somewhat less important than the long-term trend, which is what Aria is best at.  It does seem to matter how you stand on it, but I think this is true of every scale I have owned.  The website has very nice graphs of weight, BMI, fat %, fat vs. lean, over a variety of time periods (from one week up to every reading Aria has recorded).  Given the amount of data the One and the Aria collects, I have a feeling that more analytics might be rolled out on the website in the future.  All of your data is kept as private as you wish.  The Fitbit site also has a community forum, but I like the MFP one better.<br /><br />I love the integration with the Fitbit website and with My Fitness Pal.  Between those two sites, the Aria and the Fitbit One, I feel like I have a lot more tools to reach my health goals.
