Fitbit Flex FB401 Wireless Activity + Sleep Tracker (FB401) Black - No Dongle, L - Pre-Owned


Product Overview:


Staying healthy can be tricky. With the internet and its various life-sucking pits of inactivity and stasis, getting up and doing something active can often feel downright impossible. But what if the web could turn into a motivator, a knowing calculator of your body's needs, what then? The innovative, high-tech Fitbit Flex Wireless Track Activity and Sleep Wristband merges the function of pedometer and a sleep study, calculating steps and distance walked, calories burned, as well as hours and quality of sleep. Better yet, the FitBit Flex wirelessly uploads data to your computer, iPhone, and other select Bluetooth 4.0 devices.


Key Features:



  • The wristband tracks steps, distance, calories burned, and active minutes. The Fitbit Flex Wireless Wristband is the ideal partner and will help you reach your goal!

  • Log food, weight, and more on Fitbit's website or apps. You can set goals, view progress, and earn badges as you go along. LED lights show how your day is stacking up against your goal.

  • It monitors how long and how well you sleep. It also features a silent vibrating alarm that will wake you in the morning (not your partner).

  • Enlist your friends and family in helping you reach your goals by sharing your stats, creating fitness challenges, and taking a group leader board challenge.

  • Syncs automatically with Android devices (Samsung Galaxy S III, Note II, and more), as well iOS devices (iPhone 5, 4S, iPad 3rd gen., iPad Mini, and more) and PCs and Macs. The wristband is Bluetooth compatible and set up for wireless connection (dongle is included).

  • Flex syncs with popular fitness apps for an integrated fitness regiment. Apps include Sparkpeople, LoseIt!, MyFitnessPal, MapMyFitness, Runkeeper, and Endomondo.

  • The Fitbit Flex wristband is easy-to-wear, slim, and very comfortable. Wear it all day and night - even in the shower!
