It is possible to use it to fix any cammera, not only mobius. The standard screw make it possible. It can also be used for different applications (not only the helmet) since the velcro strap can be attached anywere. There is also a base with an sticker to fix it in a glass or what ever you want.Don't think to buy if you have mobius. It can be necessary any time.......Fits my helmet without trouble. Keeps the mobius firm enough against the helmet.Works as expected but the screw was slightly too long, had to grid it one or two mm shorter.
