[Closed] Anyone use an Oregon Scientific helmet cam?

I was lucky enough to get an ATC5K as a christmas present, only had one ride with it so far but looks like it could be pretty handy (especially considering the price).

Only gripe so far is the helmet mount, which seems a bit on the sloppy side! I've got the base mounted pretty tightly to the helmet, but the camera seems to have a bit of play in both up/down and side/side directions (elevation and azimuth if you prefer). I assume they all do this? Has anyone managed to elimate the play?

I'm thinking that some thin material underneath and down the sides will work, but always handy to see what others have done first.

Cheers,
Mark
