Review on BOBLOV HD66 Body Worn Camera - IP67 Waterproof 1296P Wearable Camera - Audio & Video Recorder - 170° Wide Angle - IR Night Vision - 360° Rotation Clip - 64GB Storage by Tutan Beatz

Received my block and got it working. My machine came in an open box, apparently missing the instruction manual and CD. The device worked fine until it was full. I downloaded and deleted all videos. Now the camera stops recording video because it shows "Card full". No video files are displayed in the camera. My email to the company said to reformat the card. How can I do this without a disc, and if the camera doesn't show any video files, why reformat!
