The 4 Stars isn't the Aria's Fault...
Okay, there are some flaws that all of these scales. They use inductance to measure body fat %%. I'm not going to get too deep into the electrical definition of inductance - but for the sake of argument - it's measuring the electrical resistance between one foot and the other. It does some pretty fancy calculations based on your height (that you tell the software) - your weight, which it measures pretty accurately... and it tries to figure out your body fat percentage. Then, it does some more math and will figure your lean body mass.<br /><br />Overall, it's a pretty neat technology... but it's not 100% accurate. Now - just to be clear - it's not a flaw with the Fitbit Aria specifically, just in all inductance scales. There's no way for the scale to know how hydrated you are... if you're retaining water or excessively dehydrated - it throws off the calculations between fat mass and lean mass. I've had it jump 3-4% body fat in the space of a day. It's best to watch trends in the readings... it's not a medical grade device, but if you weigh yourself at the same time every day, get into a routine... then you can watch trends in your body weight and what it says is your body fat %%.<br /><br />Knowing that - I'd still recommend this scale.<br /><br />It's fairly simple and straight forward to set this up - get it connected to your wireless network and associated with your Fitbit account. Just follow the instructions closely. It will connect up to your wireless network - it'll sync with your Fitbit account almost instantaneously.<br /><br />Fitbit has a very very nice ecosystem of health monitoring products. For me, it's not just the bands and it's not just the scales... but you can use their app to view how you sleep, how active you are, resting HR... and with this scale, your weight and (relative) body fat %%, lean body %%... and you're able to have some objective numbers to watch.<br /><br />I'm giving this 4 stars because as neat as the technology is, it's not perfect, but just to be clear, it's not a problem specific to the Aria
