Fitbit Flex review

We have truly entered the era of the quantified self. Editorials are shouting it from the rooftops, technologists are snickering "I told you so" and you, dear consumers, are just eating it up. If there's some sort of personal metric you'd like to monitor and view in a pretty little chart, there's a product out there to help you do it. Now, that doesn't necessarily reflect a mature market rather than a fleeting fad. But we'll say this: companies both big and small are offering a number of products for this growing niche and some have built their entire portfolio around a lineup of personal tracking devices. Fitbit is obviously one of those companies and, with the One, Zip and Aria WiFi scale already on the shelves, it's got a pretty robust set of options for those looking to turn their entire lives into a collection of infographics. With the Flex, though, it truly rounds out its offerings with a wearable band in the style of the Jawbone Up and Nike FuelBand.

There are, of course, a number of differences between all of these products -- not the least of which is price. At $100, the Flex undercuts its most direct competitors by at least $30. There's also support for Bluetooth 4.0, which delivers wireless syncing on both Android and iOS. The question is, does the Flex deliver enough at that price point to make it a clear choice?
