It seems to work well but the battery life is only 3 or 4 days if you wear it at night. Revain suggests that you buy a face protector with it. I did but the face is slightly domed so the protector doesn't lie flat and collects dust around the rim. If you don't use a protector the face gets scratched up easily.
