This product really leaves something to be desired. It includes 3 different sizes of neck straps that do not work. The stupid camera is too small for my neck and too big for my wife's neck even with rubber straps. Second, he writes badly. The images will eventually not be visible. In the test video I made, my wife's head disappears. The creators of this camera have made many improvements. One should be ashamed of what they have made available to the public.
