Fitbit Flex 2 Fitness Wristband - Magenta

The Fitbit Flex 2 is a water-resistant, all-day activity and sport tracker that can be on your wrist or, using a separately pendant, around your neck. This stylish accessory tracks your steps, distance, calories burned, and more. It utilizes SmartTrack technology to automatically detect activities like running, sports, and aerobic workouts, then sends those exercise summaries to the Fitbit app for review. Additionally, the Flex 2 automatically measures your sleep quality and features a silent alarm that vibrates to wake you up, rather than beeping which could wake others. The Flex 2 uses Bluetooth 4.0 LE to sync your data wirelessly with compatible devices whenever it's within 20' of them. Bluetooth also allows you to receive smart notifications whenever you receive a call or text. Both small and large wristbands are included to ensure a comfortable fit, as is a charging cable.  Feature- Fitness Tracker Wristband & Accessory- Tracks Steps, Distance, Calories Burned- SmartTrack Exercise Recognition- Auto Sleep Tracking- Swim- and Shower-Proof- Syncs Data Wirelessly- Reminders to Move- Smartphone Notifications- Works with Companion AppSpecificationProduct Model:Fitbit Flex 2 Fitness Wristband - MagentaSystemCompatibility:Bluetooth LE-compatible devicesWirelessBluetooth:V4.0
