Fitbit Flex activity tracking wristband now shipping for $100

Fitbit's freshest fitness fob, the Flex wristband, may not be the most comprehensive activity tracker on the market, but it does deliver quite a bit of bang for your buck, as we discovered during our review. The company's latest gadget is set to compete with the Nike FuelBand and Jawbone Up, but at $100, it's more affordable than either of them. A single Benjamin buys you step, distance, calorie and moderate-intensity cardio time tracking, with wireless Bluetooth 4.0 syncing to Android and iOS apps. It can also keep tabs on your snoozing habits, including how long and how well you sleep, offering up tips should you need to make some tweaks. There's also a vibration alarm that'll shake you awake without disturbing others. Fitbit Flex is available through major retailers and at the source link below -- for an up-close work at how it works, be sure to check out our full review.
