I have a contour.. Really like it. I mount mine to my helmet also made a pole mount for it Takes great video and has been durable. I have the older Roam.. Only negative is they don't have as many mounting options and accessories as the gopro.. Also there software isn't as robust. I think the contour takes better video than the gopro but thats just me. Love how you can rotate the lense and get a nice wide angle. Also like the one touch on and off. Battery life is solid. I have used it also for track days on my car and again takes really nice smooth video.
