I could certainly see the possibility of the camera going through a vent hole if you landed right on it. It would be a freak accident, but then I guess this one was.I've got go-pro mounts on all of my ski helmets, I've had plenty of crashes not once has my helmet failed on or around the go-pro mount, nor has the camera caused any additional harm, they snap off nearly instantly, I have a leash setup on all of mine
load of rubbish if you ask me
