I bought these for flight training to record video of instruments and landings. They look good but all entries are large and not straight. You need to position the camera better. You have to look down to get a good view, the nose guard is also too stiff and pulls the goggles away from your face a bit. Totally dissatisfied with this product. It only lasts about 30 minutes on a single charge, and the videos are snippets that don't continue to play.
