    Fitbit Aria WiFi Smart Scale is rated 3.2143 out of 5 by 14.
    Rated 5 out of 5 by from Easy set up, works great My wife gave me a Fitbit Force and us this Aria scale for Christmas, so this is a 24 hour initial review. If we have problems later, I'll update this review. Setup: easy, less than five minutes. It took me longer to fetch the WiFi password than get the scale connected. I followed the directions, used the Fitbit setup website/software (PC), placed the scale close to the wireless router (the scale was about 10 feet from the router) as recommended by the directions, and it connected. Accuracy: I haven't tested the scale with a known weight or other check. However, when I step on the scale the results are as I expect. It is a longer process than our old analog scale - the Aria also measures body fat using a small electric current, so it takes several seconds. My wife used it without a Fitbit account (guest mode), and liked it. In guest mode, it measure weight but not body fat. Do I really need a scale that sends data to a webbased app? No. Does it simplify my health monitoring and interesting? Yep.

    Rated 4 out of 5 by from So far so good The Aria works as described. I had a little trouble setting it up initially, however, I'll attribute that to my network. Once I got it talking to my router, things have been stable since. My weight numbers are generally consistent and they match the numbers I get from another in house scale. The body fat percentage numbers vary from day to day, but not so widely that I have too many concerns using this a tracking device. I may ask my doctor if I wanted a very accurate measurement, but for my needs, this fits.

    Rated 4 out of 5 by from Excellent Training Tool I've been using this scale for about seven months now. Setup in my case, fortunately, was easy and problem free. I followed the prompts, it recognized my home wireless network, and it's pretty much worked ever since. I can appreciate the frustration of owners who did not have a similar experience. Frankly, I was surprised it worked as well as it did. I gave it a 50/50 chance before I started. About 10% of the time it will fail to transmit data to Fitbit. Step on it 30 minutes later and it works. It hasn't been enough of a nuisance for me to contact Fitbit. Data that does get transmitted shows up with no problem on the desktop and the iPhone app. The iPhone app is a bit flakey in layout, but with persistence you can get to what you're looking for. As far as accuracy, I think the weight is pretty dead nuts on. The body fat percentage, probably less so. I've never independently verified it. So there's just no way of knowing. This spring and summer I used the scale almost every day to track my weight and body fat in preparation for two weeks of road bike riding in the mountains of France. As a training tool, it works great. It would be the first thing I'd step on after getting out of bed in the morning (lit display is nice). As I noted previously, the body fat absolute numbers are suspect, but during training they correlated well with physical changes in my body. Overall, I'm pleased with how it works. I'd have given it five stars if it didn't have the periodic connection problems.

    Rated 4 out of 5 by from It's a scale! It's a scale. A pretty (and, yes, expensive) scale. Don't expect it to lose (or gain) fat/muscle for you, that's your job. Setup: save yourself a lot of drama, based on review comments both here and online. If you don't have an iDevice, find a friend who does and have them come over when you set it up. DO NOT USE THE SOFTWARE FROM FITBIT to try to set up the scale. Just use the online setup via iDevice and everything goes smoothly. I was up and running < 10 minutes after opening the box. Ease of use: Simple. Step on, wait, once you see the numbers show up (~ 30 seconds?), step off. Go to the app and check your stats when you want. I'm a data junkie; I track everything. With the Aria, no more moving data around, which is what I was looking for. Accuracy vs Precision: Weight and bio-readings are consistent so far. I happened to be able to compare my weight on the Aria to my doctor's scale (w/in 24 hours of each other) and the Aria was within 0.5# of the doctor's reading. I will see how it goes in the next 6 months, my numbers should start changing week to week, based on my last run up to marathon training period.

    Rated 5 out of 5 by from Works well as advertised. I picked up Fitbit Aria to pair up with Fitbit Force that I have been using since beginning of the year. I was in need of a new scale so timing was perfect. So far I am really enjoying the product. Wireless synch up of the data makes it very convenient. Body fat % was an eye-opener. Prior to the purchase, I was a bit concerned about the setup as that seems to be the biggest complaint about Aria. But I did not run into that issue. I was recommended to use smartphone to set this up. Using this method install was quick and smooth. If you are using any Fitbit product, I would highly recommend Aria as a combo package.

    Rated 4 out of 5 by from Easy way yo track weight and BMI I like the ease at which I can jump on to get my weight and look at the reading on the Android app later. The body fat % does vary a good bit even in one day. I have read that this type of measurement is not the most accurate so I just watch the general trend of it and not the specific measurement of the day. The weight seems to be accurate and the automatic recognition of each user is handy too.

    Rated 1 out of 5 by from Two Arias and two routers later I really wanted to like the Aria. I have a fitbit, my boyfriend has a fitbit and he has the Aria too and they all work great. I did not have such a success with my Aria though, in fact I had zero success with it hence my poor review. I got my boyfriend his Aria as a gift, he took it home and within minutes it was working. It still is. Mine is quite a different story. I followed the instructions, but the Aria would not connect to my wireless network no matter how many times I repeated the process. It was not easy to repeat either because every time it failed, it would also change the settings on my laptop just enough that now my laptop would not connect to my network either. So I had to disable the wireless adapter on my laptop for every repetition. Eventually I gave up and my boyfriend tried - still no success. We are both technically savvy being software engineers, so we really tried - the security on the wireless network, the name on the wireless network, the characters in the password, the connection type (g/b/n) - they were all suspect and we changed them all according to the specifications on the fitbit site. Alas, even using our cell phones and his laptop in case it was mine that didn't work - nothing helped. Finally, we decided the scale was bad and we got a second one. Still no success. Perhaps it was my router? So we got another one of those too and repeated the process. That scale is sitting on my desk and it is ready to go back to the store at this point. Frankly, if I had been able to get it to work, I would not have rated it 1 star because I know from my boyfriend how much he likes his. But it doesn't make sense for both of us to fail at setting it up when it's supposed to be easy. We didn't just fail a few times either, we never succeeded. I still have no idea how I could possibly ever get it to work.
