I have had this camera for a few years. I feel like I have really gotten my money worth for it. Not only does it have very high quality video, but its easy of access is great. The camera is operated by the simple switch on top of the camera. This way you can know if the camera is recording just by feeling it.
I really like how discrete this camera is. It fits on the side of my helmet and is lightweight and discrete.
The one main fault of this camera is its inability to switch between photo and video on the go. You have to do this on the computer.
My personal opinion is this beats out a GoPro for POV helmet footage, just because it is a lot smaller and more convenient. The GoPro on the other hand does have a lot more capabilities for other types of video and mounting. If you are looking for a camera for POV skiing, biking, or skating footage, I feel like this is the one.
