    Fitbit Aria WiFi Smart Scaleis rated3.2143out of5by14.
    Rated5out of5byfromWorks 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.

    Rated4out of5byfromWorks as advertisedDidn't have any trouble setting up the scale on the network. It is very consistent with our old scale. The BMI values are probably not very accurate, but I still look forward to watching them get smaller. Only downside, is I haven't figured out a way to NOT save a value... so even the "day-after" readings get saved and reported on my FitBit progress screens. I suppose that should offer some motivation to be better when eating out...

    Rated5out of5byfromEasy set up, works greatMy 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.

    Rated4out of5byfromExcellent Training ToolI'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.

    Rated4out of5byfromIt'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.

    Rated1out of5byfromWifi pretty naiveThe Apple Mac app tries to shuffle wifi connections, unsuccessfully in our case. It tried to connect to various random protected networks of my neighbors.... not clever. The PC web site works, has user switch wifi to the Aria base station and then spec the network. Appears that our 128 bit WEP key is persona non grata -> appears to want a simple string. Everything lines up, the scale finds the network, and then.... "no synch". Not useful. Since changing the WEP password on our base station is a non-starter, looks like back to REI it goes.....

    Rated1out of5byfromDoesn't work...After 4 hours of trying to set up our new Aria on two computers and a phone, I've given up in frustration. It would appear that the device is unable to detect/connect to my home network even though we have 6 other devices that do. I'm pretty frustrated - I'm a software engineer. This shouldn't be this hard. I have, of course, logged a support case with FitBit. Sigh.
