SAN FRANCISCO -- Fitbit said it is investigating after a woman claims her device exploded and burned her.

A Fitbit measures steps walked, heart rate and other personal fitness data.

Dina Mitchell from Milwaukee said she suffered second-degree burns after wearing the device for only two weeks.

Her doctor had to remove pieces of plastic from her wounds.

Mitchell said the Fitbit appeared to be working fine before it exploded. Fitbit said it is not aware of similar complaints.
