I have used this in the past and loved it. I haven't found one for my PC that I like as much, but I will report back if I do.
For those who are considering buying it, make sure you get a handlebar mount and a floaty compartment. They aren't that expensive and are very useful. you can attach the handlebar mount to just about anything with a little ingenuity
I don't like how there is barely any audio for the waterproof case. When we go out on the boat it makes sense to have the case and floaty on in case it goes flying, but then the audio is all muffled. That's probably my only complaint.
Anyone use the Go Pro app with the Go Pro's built in WiFi?
