Summary: This lasts for hours and hours. Your SD card will run out before the battery does. Great laser-level sighting to arrange camera too. The only downside is that it is too big to mount to a helmet without looking bizarre. Get a bike attachment for it.
Summary: Reliable, sturdy and clear. An overall good product. Lots of mounting options, clear video and sound. Mainly used for airsoft and so far no complaints. Would be awesome to have switchable battery to extend recording time but other than that, great camera.
Summary: When I bought this there was a spot on the inside that was right in the middle area of the picture. I took about 30 min figuring out it was not under the protective cover but under the lens which you cannot un-screw. I was very pissed blowing canned air and parts cleaner in/on it and then realized from many years of experience that it was a VERY small bug which had crawled in, got trapped and died on the lens.
Summary: I use this camera as a helmet cam when riding and dash cam when driving. Picture quality is excellent. Doesn't get much better than this when compared to the overpriced overhyped stupid gopros. Only complaint is it does not get good quality video in low light, but you can look at youtube and watch samples. Its not good at night. But then again unless you drop a 1000 bucks none of them are.
Summary: I hate that this company has gone out of business. But if you can still find one of these cameras and want a good quality action video image, but one! I have four of these cameras (and yes I own GoPros also) and love the Contour. Biggest advantage is the shape and size and mounts (and VERY clear video image). I bought this one as a gift and they love it. I use the model with GPS in my car as a dashcam.
