Was searching for a GoPro Hero4, but came across this cheaper alternative. Haven't received the item yet, but I have purchased it. I do general mountain biking have a camera mount on the bike and thought this would work perfectly, at a significantly cheaper price. This version comes with the selfie stick too.
