I took this down to Fruita for a weekend of mountain biking, and had some pretty good results with it. They have added a software update to allow the camera to film inverted, which is awesome! The only downside to that, is you need to make sure to select that option on the camera every time you turn it off. If the camera times out, you do need to re-set it to inverted. I did a run at the lunch loops and a run on PBR at 18 road and did the shake to edit feature. This works really well, however since it mostly tracks speed, it also highlights any time you slow quite quickly, leading to some sub-par footage. The upside is its quick and easy to remove those clips and add better ones in to your video. Quick, easy, and the ability to view and adjust camera through your phone and change some settings is great. Size is a bit bulky compared to others, but under the handlebars it is hardly noticeable.
EDIT: Video only uploaded in a max of 240, not sure why that happened, but it was not intuitive to make sure it published in a higher quality.
