I bought this mini camera to film from my bike. In fact it is more interesting to record scenes in "spy" in society, as you will shoot from a moving vehicle, especially when the speed increases. She quite captures the sound, but against the image, + speed - high (50 km.h) becomes "undulating", at least with mine. This remains a gimmick, but for 15, you can not have better The battery life is relatively long. The Start button is broken, so I chose to activate it via the switch reacts to the sound.
