This simply chic hinge bangle Fitbit Bracelet is classy, versatile, and full of style! This bracelet goes well with anything and keeps you looking put together and perfectly accessorized all while hiding your Fitbit Charge activity tracker. Part of the fashionable and functional Fitbit Jewelry collection by FUNKtional Wearables. HOW IT WORKS: We engineered a fashionable alternative to securely hide and fit the FitBit Flex tracker perfectly! This concealed pouch means that the Fitbit Flex will not dislodge from under the bracelet or pouch. So rather than wearing the plain plastic band that comes with your Fitbit Flex, you can simply use this elegant bracelet to dress up your look! QUESTION: Will the FitBit be as accurate if worn in a necklace or a headband? ANSWER: YES! The Fitbit engineering team has developed tracking algorithms to ensure accuracy whether the Flex is on your wrist, your core, or around your neck. For best performance, make sure that your "dominant hand" setting is on "non-dominant." Check out our other necklaces and bracelets designed to be worn with your FitBit! *Not recommended to wear during work-outs or sleep.
