I have yet to try it out. I`m not quite sure about the "sticky" mounts as the is not a lot of contact surface with my cycle helmet. I also have more than one bike so the minute I stick a mount on one bike, there it will stay. So, I may have to buy one of the bike mounts as I will also be cycling abroad this year and will be hiring bikes when I`m away.
Having said that, I do have some very versatile velcro loops that I could use meaning I can mount the camera right on the top tube between the hoods. May not be the most aesthetic of looks but means I can very easily transfer the camera from bike to bike. Spend all that money and then essentially cable tie it to the bike!
