I bought the belt as I was to have the idea of the Action Cam on the shoulder interesting. Works wonderfully. Unfortunately, the Cam variant on shoulder is not suitable for every action (at least the way I operate) In any kind of Action where the upper body is exposed to continuous strong agitation, this belt is not suitable. The check cam angle, vibration and no way that the cam has slipped not make the belt while a great idea, unfortunately, quite suitable action. 2 person kayak (if you do not have to paddle) for the belt would be great. :)
