I know this is kind of old, but I have four of these. They are pretty good. The only serious issue you have with wind noise is if you don't use the waterproof case thinger. Even still it's not all THAT bad to be honest. I mean, what do you expect out of a 300 dollar camera?
Picture quality is amazing, even on the lowest setting.
YouTube sucks as far as video quality goes, but here is an example. My big ass getting into the freeway. I made this video just testing out the camera before I went out to the track, disregard the watermark in the middle of the video, I didn't have editing software then. I've not really made anything 'cause my FD sucks and my drift car isn't finished yet. Anyway sorry for ranting, here's a couple vids.

As you can see, the quality on the cameras is actually pretty damn good. They are totally worth their price if you ask me.
