I bought a GoPro ages ago, tried it on a few rides, and decided the picture quality was, basically, crap.
I managed to snap up one of the Argos AS30s a few months back and have tried using that a bit more often. I’ve come to the conclusion that it really needs a bit more effort than I’m currently giving it as I’m not really into stopping and starting, setting it up etc. Short videos when stationary can just as easily be shot from my phone or compact camera. However, I do have a couple of (long-delayed) projects that might see the AS30 being used more productively.
Edit: you could have my old GoPro for the price of postage if you just wanted to play around with it for a while. You’d need to get a mount or two though).
