Some people looking to ramp up their New Year's health and weight loss goals with a new Fitbit Force activity tracker got more than they bargained for — bright red rashes.
Following widespread reports that users of the wrist-worn device were developing strange skin irritations, Fitbit apologized and promised to issue refunds to affected customers.
In a statement, a Fitbit spokesperson said a"very limited" number of Force users experienced skin irritation, possibly due to an allergy to nickel found in the stainless steel used in the device.
"We are sorry that even a few consumers have experienced these problems and assure you that we are looking at ways to modify the product so that anyone can wear the Fitbit Force comfortably," the company said. "We will continue to update our customers with the latest information."
Those who have experienced skin irritation after using the Force should stop using the product immediately and contact Fitbit at force@fitbit.com, the company said. Affected customers can get a full refund or swap out their device for a different Fitbit product.
A number of users have taken to Fitbit's online forum to voice complaints about the product and post photos of their irritated skin. Some have also expressed frustration that Fitbit hasn't been more transparent about the issue.
While Fitbit blamed nickel, the jury is still out as to what is causing the problem. The Huffington Post interviewed more than a half-dozen affected Force wearers, some of whom said they had no known allergies, and have worn metal watches without any irritation in the past.
According to the report, symptoms have ranged from "red, itchy skin to painful blisters that would ooze or bleed." Some Force owners said they sought medical care and were prescribed prednisone and antibiotics to clear up the rashes.
Meanwhile, activity trackers and other wearable tech were one of the major trends we saw at last week's CES in Las Vegas. For more, check out Feel the Burn With These CES Fitness Gadgets and our video from the show floor below.
