Fitness tracking company FitBit is recalling, and ceasing production, of its activity-tracker wristband called "Force" after users complained of a rash they'd attributed to the device.
Co-founder and CEO James Park said that the recall was voluntary on the part of the company, and that customers would be issued a full refund.
Some customers had previously reported issues with the Force, and FitBit at the time said it would replace the device or refund money for afflicted customers. The latest measure was taken out of an abundance of caution, Park said in a statement.
"[S}ome users may be reacting to the nickel present in the surgical grade stainless steel used in the device," Park said in the statement. "Other users are likely experiencing an allergic reaction to the materials used in the strap or the adhesives used to assemble the product."

Park noted that only 1.7 percent of force users experienced any kind of skin irritation. Users of the product can go here to return the device.
