Anyone used them before?

i went for the 480 xtreme package so i can use it on my bike aswell as other activities i do.

Let us know what it's loke it'd be great for track days. I'll be able to show everyone how slow I am.

lol, will do.

the reason i went for that one was because i can use it for other things such as army exercises and the like. its a bit more expensive than others but has an 18 month warrenty and claims to be pretty damn tough.

another one i was looking at said dont attach it a frame of a bike as the vibrations can damage it! id rather have a tough camera :)
