I got a SJCam M10 (

) because I got fed up with close passes on my commute - without evidence there'd be nothing I could do about them but the police have spoken with 2 close pass drivers on reviewing my footage so far and are about to discuss a third reckless pass on a blind bend with me. (see

for one of them). Most of the time I delete footage daily but sometimes I'll upload something.
One thoughtless driver at a time, it might make a difference but at least I can now sometimes do something about dangerous driving.
In the waterproof case the sound is hopeless so the footage is pretty much just video. I bought the M10 because I didn't want to spend a lot on something which I might have got bored or fed up with, and because it is fairly compact but it is still too big & daft to go on the helmet. It won't catch every daft manoeuvre but I'm happy to compromise. The actual footage is a lot better quality on a PC as it seems to lose quality when uploading to YouTube. Unless it is raining I can clearly make out registrations from pausing the footage. The still images are very useful.
I run it under the bars so it is fairly discreet. It doesn't look into car windows like a helmet camera would, so it doesn't show who is on the phone very often. If money permitted I might look into a Drift Stealth to go on the helmet as they look compact, and have good battery life.
