My GoPro came with a strap helmet mount that adapts to most helmets thru the vent holes. I have never used the adhesive mount. I have another K-Edge handlebar mount with the Garmin mount on top and the GoPro screw mount below. Both work fine, though the helmet mount is a little top heavy with the camera. If your helmet has the bug screen or honeycomb liner (like my new Smith helmet) the universal strap mount won't work, and then you use the self adhesive mount.
