I was all set to buy a Contour Roam 2 until I found out they went under. Thankfully was recently over in Canada and managed to pick up a new R7 Replay 1080 for a really good price (a fraction of the horrible UK price). I've been pretty damn impressed with it so far. Footage in both 1080p 30fps and 720p 60fps is very impressive, the FOV is great, although you could argue the colour is a lil over-saturated. So far I've only used in on the field with a homebrew goggle mount which I made by using parts of one of the included mounts and drilling a hole through the lense clip on my vForce Grills. Here's a pic of it:
The camera is really light so I didn't find that it upset the balance of my goggles, tbh I didn't even notice it most of the time. Unfortunately the day I used it I was using my pump gun, which as it's right feed meant that the majority of the time the target I was shooting at was blocked by the hopper. I'm playing another walk-on this Sunday where I'm gonna try with the included R7 mount on my Ego. As it's the standard mount it's unable to fit on the Planet Eclipse type of feedneck. Thankfully it's possible to clamp it onto the loader feedneck. Here's a pic of how that looks:
The included 4GB micro SD card isn't enough space. Although the camera has a battery life of over 2hrs recording I only managed less than 40mins of recording at 720p/60fps before it was full. Thankfully I have a 32gb card on it's way. One thing that is cool about it is that the memory card structure and video files are completely compatible with iMovie on the iPad, by using the SD Card adaptor I have been able to import footage onto my iPad for editing.
