The goal was to have a 2nd attachment for my wife because I have already that I bought at Decat 'on my helmet. well it has nothing to do. The straps are complicated to tighten properly, I have to sew the straps on the plastic rings to avoid losing my GoPro in action ... :( And there is no vibration and helps make good contact on the helmet gum under the support. Cheap ... it is clear ... but not great either.
