If you are looking for a "smart scale," that is, one that reads your weight and body fat percentage, then syncs it to your cellular device so you can track it, you may be considering the Withings WS-50 or the FitBit Aria. I researched both of these before making my purchase. I chose the Withings, because it was heavier, bigger, and had a sharper display. Overall, after reading the reviews I believed the Withings was a higher quality piece that would last longer. The price point also led me to believe it had higher accuracy, although I cannot provide a comparison to confirm that. I saw the reviews beforehand indicating it may be a hassle to set up, but since I am relatively technology-savvy that did not phase me. I figured that once I got past the set-up the Withings would be a longer-lasting product.
It took several days before I got an email back from Withings customer support. They do not have a phone number published for customer support, so email is the only method. I did receive a brief email back the next day with a link to online set-up (which is commonly found on their website and in the set-up directions), which did nothing for me since I already had that link. I emailed back, but getting a second response took way too long. I was able to not only return the Withings scale, but order and receive the new scale (a FitBit Aria). My Aria was long since ordered, received, set up, and functioning perfectly before I finally got a response back from Withings. My suggestion to Withings is that use phone support to handle customer service.
