Fitbit Inc., a company that makes wearable fitness technology, issued a voluntary recall this week of its Force wristbands after some customers reported skin irritation from using the device.
James Park, co-founder and chief executive officer of Fitbit, said Thursday that about 1.7 percent of Force users have reported skin irritation.
The $130 Force wristband, which hit retail shelves late last year, wirelessly monitors sleep and daily fitness activities, such as sleep quality, steps taken, active minutes and calories burned.
After an independent investigation of the claims, Park said test results indicate that Force users may be experiencing an allergic reaction to nickel, adhesives or other materials in the wristband. The tests have not found problems with the device's battery or electrical systems, according to Park.
Fitbit will discontinue the Force model and offer a full refund to its customers, Park said.
