"Dash Cam with SD Card(32G) Carigogo 1080P Full HD Dash Camera for Cars Recorder 3.2" Screen 170°Wide Angle, Night Vision, G-Sensor, WDR, Parking Monitor, Loop Recording, Motion Detection" Granted it is not the most expensive. Cost me $19.99. It has been working fine. Records in 3 min segments. During a road rage incident, I had to brake hard and steer to the right to avoid a collision. When I checked the footage, the segment before was recorded, but that segment was not recorded or it was damaged. It did not record again until about five minutes later. Any idea of what happened. Thanks
