Rated 5 out of 5 by from Great scale I recently purchased a Fitbit Flex and saw that there was a corresponding scale that syncs wirelessly with your Fitbit account. I ordered the scale in black and have been very pleased. One caveat, it is a little pricey as far as scales go. Set up was fast and easy. The thing that took me the longest was to find my WiFi password. Other than that, set up took under 3 minutes. I know you shouldn't weigh yourself every day, but I love weighing in first thing in the morning and then after a hard cardio workout. I love how the information - weight, body fat percentage, and BMI - are synced to your Fitbit account so you can see your progress. If you have the means, I highly recommend.

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 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 1 out of 5 by from great idea, poor execution and support i tried for 10 days and 2 different scales to get this to connect to my network. their tech support isnt terribly responsive. especially given that it costs 3 to 4 times as much as similar scales. i have their fitbit one and its a joy. easy setup and it just works. i took a chance on this thinking that it would work as well, but it doesn't. while trying to self diagnose the issue online i came across reviews that said that its not that accurate either. i cant speak to that since i never got it to actually work, but based on that, its inability to function as advertised and the high price of the scale, it went back to REI. they were great about the returns and continue to be a great place to shop.

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 2 out of 5 by from BMI reading errors I purchased a Fitbit Charge HR in early February. Shortly after, I purchased the Fitbit Aria smart scale. I would classify myself as someone that is fitness focused. Measuring and charting my BMI intrigued me. The scale looks very sleek. It appeared to provide a very accurate read for my body weight. However, 8/10 times I would receive an error that it was unable to read my BMI. I researched this issue online, and it appears as though this is an ongoing problem with the Aria. Most sites showed that the error was a result of either the scale being dirty (if that is the case clean with a paper towel and windex) or a user's feet being too cold. I cleaned the scale and tried to warm my feet, but I still received the BMI error far too often to justify paying $129 for an item that only performs its intended function a fraction of the time it is being used. Because of that, I returned this item. I would not recommend this item to others until that issue is resolved. Additionally, even though the scale is wifi capable, it would be nice if it were also able to sync with a fitness tracker or smartphone through bluetooth connections.

Rated 1 out of 5 by from Incorrect reading of the body fat% I have been using FitBit products for about 4 months now and I loved the FitBit One and my husband got his FitBit Flex (also inaccurate). Since my husband is a gym junkie, he thought this scale would help determine his progress because he is 5.8, 198lbs and very muscular. The simple weigh scale would only show the change in weight and not body fat percentage. This scale was utter disappointment. According to the scale, he was 45% fat which would translate to him being extremely obese. So that was a big fail and we stopped using it and returned it back to REI after just a week of use.

Rated 4 out of 5 by from Great scale! I've had the scale since January. Setup was not difficult, but takes a bit of effort. Sychs pretty well with the Fitbit iPhone app, with some delay of having the info displayed on the main screen. Seems accurate for weight. Not sure about body fat%, but is as good as any other household scale. Pricey, but a nice way to automatically log your weight and bodyfat%. A little ironic that it allows me to be lazy about the tracking.

This Aria scale says not to use if I have a pacemaker or internal medical device. I have a Medtronic implanted defibrillator, wear a Fitbit Surge. Is it actually dangerous for me to use this?
