Loving our Fitbit Aria Wi-Fi Scale
We purchased this scale for our whole family use.  Being able to track multiple people simultaneously was a big plus.  As others have mentioned, setup could be a little easier.  I followed the written instructions and got stuck at the same point trying to complete the setup.  The Fitbit support staff responded very quickly to my support request and provided alternate on-line instructions for set up which worked the first time.  Since then there has been no problem with the scale working and uploading its' data to our Fitbit accounts.  Highly recommended.
