What’s Included Removable Fitbit Flex™ tracker 2 wristbands (small and large) Charging cable Wireless sync dongle

Sensors and Components 3-axis accelerometer Vibration motor Display LED display with 5 white indicator lights Tap twice to see progress against your Main Goal Tap rapidly for 1-2 seconds to start or stop sleep tracking
Water Resistance Flex has been tested up to 1 ATM meaning it is sweat, rain and splash proof. However, the device is not swim proof. We also recommend taking Flex off before showering because, as with any wearable device, it’s best for your skin if the band stays dry and clean. Care If the band gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Clean the band with a mild soap-free cleanser like Cetaphil Gentle Skin Cleanser or Aquanil. Give your wrist a rest by taking the band off every now and then. Learn more.
Materials The Flex wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. Flex also has a surgical-grade stainless steel clasp
