Fitbit Flex Wireless Activity Sleep Band.

Key Features and Benefits:

• Helps you get your ZZZs
  Flex never sleeps, even when you do. Continue to wear it all night and it'll measure your sleep quality. Your dashboard will reveal how long you slept and the number of times you woke up to help you learn how to sleep more soundly. Flex also has a silent wake alarm that gently vibrates to wake you at your desired time, without disturbing your partner.
• Always by your side
  Flex is your perfect companion. It fits comfortably around your wrist so you can wear it proudly all day and night.
• Wireless sync
  Connect to any computer with Fitbit's wireless sync dongle (included). Sync occurs automatically when your tracker sits within 20 feet of a dongle.
• Sync your stats, see your progress
  Flex automatically syncs your data to PCs, Macs, many iOS devices and select Android phones without plugging in or pushing buttons. This gives you real-time access to your stats on the Fitbit dashboard throughout the day. Also with select NFC-enabled Android devices, you can tap your device to launch your Fitbit stats. It's like magic.
• Bluetooth 4.0
  Fitbit's trackers are the first all-day activity trackers to offer Bluetooth 4.0 connectivity, delivering real-time stats without sapping your phone's battery. Flex will sync without you doing a thing.
• Discover your trends
  Flex comes with free online tools and a mobile app that allow you to set goals and follow your progress through awesome graphs and charts. Log food, workouts and much more and get the inside scoop on your health. Knowing how close you are to reaching your goals gives you the motivation to reach them and aim higher.
