I have a Contour HD camera (looks similar w/o GPS info). I've had nothing but problems with it. I have some good footage when it works, but the on/off camera switch doesn't work consistantly. So I have to just shoot all the time once it is working. That's a lot of editing when I get back to my computer. My buddies switch works fine on the same camera. I'm working on getting it fixed or replaced. I choose this camera because it didn't stick out as much as the GoPro does.
I also have a problem when I turn the switch off (to stop the camera). I use my glove and always seem to open the waterproof case. Those that have the camera probably know what I'm talking about.
Vide is awesome.
