Fitbit Says It Will Make Changes to Address Complaints About Allergic Reactions

After withdrawing some of its activity-tracking wristbands from store shelves in February, Fitbit says another version of its wearable devices will not suffer the same fate.

The Consumer Product Safety Commission has opted not to recall the Fitbit Flex, provided that the company makes some small adjustments to make it safer for consumers.

The wristband now will come with a warning that it contains nickel, a common allergen used in many types of products, and a new sizing guideline to prevent users from wearing the devices too tightly.
