Fitbit Aria Wi-Fi Smart Scale: Get to where you want to be. Aria tracks your weight, body fat percentage and BMI, helping you understand and visualize your long-term progress. It wirelessly syncs so it's easy to view your stats with online graphs and mobile tools that help you stay motivated to reach your goals.
It is a requirement to have a wireless device to be able to get the scale connected to your wifi. If you have a smart phone or wireless laptop, that should work. Tracks your weight on fitbit website. No need to wait for scale to calibrate. Just step onto the scale and it measures your weight. After telling you your weight it then connects to your wifi and uploads your info to the fitbit website.
Issue I had was the device got confused during inital setup between my wife and I. To fix it had to log into the website and specifiy which weight went to which person. After this initial irritation everything else has been smooth sailing. Also, If there are two people close to the same weight the scale will be unable to tell who is who. It will guess and then allow you to accept or choose next user. Have not had to use this feature so am unsure how well it works. Just some good information to have.
What's great about it: has wireless builtin
What's not so great: could be hard to setup for novice computer users
