NaturalPoint TrackIR Review
 

Ever had that feeling you were being followed, but couldn't turn around to find out? Ever lost sight of an enemy plane because the only way you could see him was to keep him directly in front of you? There are two reasons for something like this happening. You might not know which keys allow you to look around. Or maybe it was because you were in the middle of a dogfight and couldn't take a hand off the joystick. Fellow pilots and drivers, those days are over.
