I bought one and took it back after about 3 videos...
Hate how everything looks farther away and no zoom...
I should have had several good bay videos from about 20 yards but they look like they are 100 yards... And can't hear crap on them unless your 10 feet away or a limb slaps it..
And from most of the videos I've seen ( including mine ) there's more video of the ground than anything!!
I took mine back and got a small video camera with extended warranty for cheaper and got heck of a lot better videos...
Only thing better about the go pro was being hands free..
