Wearable device company Fitbit is recalling one of its wristband activity trackers. The company is voluntarily recalling the Fitbit Force due to increasing complaints of itchy and irritated wrists. The company's CEO says the cause of the irritation is most likely an allergic reaction to the nickel that's in the tracker.

 

The 130-dollar device is intended to be worn 24-hours a day to track a wearer's number of steps, calories burned, distance traveled, and sleep patterns.
