This Hammered metal Fitbit Bracelet is a best seller. It's simple, versatile, and goes with any outfit day to night. The gorgeous hammered metal look is classy and fashionable, and perfectly hides your Fitbit Flex or Flex 2. Stretch Bracelet. One Size Fits Most. HOW IT WORKS: We engineered a fashionable alternative to securely hide and fit the Fitbit Flex or Flex 2 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 still be as accurate if worn in one of your bracelets? ANSWER: YES! The Fitbit engineering team has developed tracking algorithms to ensure accuracy whether the Flex is in its original band, or concealed in one of our beautiful bracelets. For best performance, make sure that your "dominant hand" setting is on "non-dominant."
