Then I had the idea to mount it on my helmet (is real fix with some electrical tape) and times to film the way to work, etc.. In use as a small, lightweight camera he pleased me better than me. Of course you can not hear much because of wind noise when riding a bicycle other than noise. But the images are - also with 640x480er resolution really impressive. In addition, the battery keeps loose by hour of continuous films. The sound is not really good (somehow inauthentic voices act), but, as mentioned, was not a problem in my use.
Conclusion: highly recommended as a cheap, lightweight camera for mobile use in hobby claims thoroughly. Sound is a little weak.
