Two days ago i got the new Contour Roam2 to test. It's a great form factor and performs ok in broad daylight, but it was severely let down but the low light performance and also some nasty rolling shutter jelly-ness. I liked the included mounts, and the rotating lens and laser guide are great ideas.
But, if a camera that is advertised as being water proof down to 1m (for canoe, wake boarding and wet motorbike rides etc) leaks on the first use...i'm not getting one. We tested it in a pool and although the footage was great, the camera started leaking...little bubbles gave it away. Because the battery is not removable, i just had to watch as it freaked out and died.
No more Roam2....
I'm now testing the Go Pro Hero3.... results to follow in a few days.
