The Consumer Product Safety Commission announced the recall on Wednesday, urging consumers to stop using the Fitbit Force with model numbers FB402BK, FB402BKS, FB402SL and FB402SLS.
There have been nearly 10,000 reports of the wristband causing skin irritation and about 250 reports of blistering. Officials say that the stainless steel casing can cause an allergic reaction.
Before the official recall notice, Fitbit had announced a refund program for the Fitbit Force on Feb. 20.
The Fitbit Force was sold at stores like AT&T, Apple, Best Buy, Brookstone, Radio Shack, REI, Target and other stores nationwide.
