For those in NSW I got a ticket and a fine for having a Gopro mounted to my helmet. Apparently your not allowed to have anything attached to your helmet.
Now I have it mounted on top of my tank, its good but you do loose some of the field of view over helmet mounted. And it puts your speedo front and center.
Its microphone is average but you can fix that with an external mic, the detail level is much better than most of the rivals I've tried.
