Summary: Excellent HD films from motorcycle handlebar mount .Unfortunately at 10:30 upside down position because there is no useful user information available .( & I turned the lens the wrong way for my first use ) . For the price, at least a basic user manual could be expected ! On-line the contour site is no better with complicated (for me !) downloads of film producer programs (all to be purchased & paid extra ) &. I still don't know what is necessary !!
