Good addition to Fitbit family...Once you get it connected.
I would have given this five stars if it was not for how big of a pain it was to connect to my WiFi.  It took three failed attempts before it connected.  I had to disable my phone's auto switch between 4G and WiFi and remove my auto connect to my favorite WiFi before I could connect to Aria.  As soon as my phone connected to the Aria it could not find an internet connection so it dropped it and started searching for other internet connections.  I have installed 3 Nest products and never had that problem.  Aria does not come with any instructions, so if it does not work the first time you have to go through the Fitbit support site on the alternate ways to connect.  There is no way to configure the Aria manually on the scale so you have to pair with another device like a phone or tablet or laptop only.  Once you get it connected to WiFi life gets easier as you can go online and update users.  I don't have multiple people using my scale so I can not speak to how well it recognizes different users by weight.
Rating: 4 stars
