The camera is tiny, about the size of my thumb! and the quality of the video footage is surprisingly good for such a small and cheap camera.
I would love to give this camera a 5* review however the mounts and brackets provided are of very poor quality and there is not much use for it as a sports or action camera if you cant attach it to anything.
I have only used the camera briefly ( mainly for test footage ) and the helmet mount has broken after only about 3 uses.
I have also had to replace the screws on the clip as the ones provided weren't holding firmly.
Furthermore the instructions were barely in English and the software provided did not work, however with a few searches on google for "md80 software" and "md80 instructions" I found what I needed.
