Summary: Overall I am happy with my recent purchase. Haven't tried out yet but have got it all setup. I only noticed one issue. If anyone has used their gogpro camera before and ever ran out of battery, you probably went and purchased the extended battery pack. That battery pack will not fit flush against the harness and ends up pointing at a downward angle. I have the gogpro hero 2 camera. I know the hero 3 is thinner, but don't know if it will fit.
