At last here is my review of the Smartcam car cameras.
If you are in the UK and you want a cheap dashcam then either of these cameras are definitely worth your consideration. The prices include post and packaging...but more importantly don't include the unwelcome and often unexpected extras, like Import Duty, VAT and 'handling fees' that you can sometimes incur when buying items direct from China.
Video Review below.
NOTE---- Youtube has had a seriously detrimental effect on the video quality from the HD cam - I've therefore uploaded a daytime sample clip here (right click and save) for you to download and play on your machine to see what it really looks like. This is an unconverted raw clip straight from the camera, trimmed for length.
UPDATE 10/4/12 - As requested, here is some night-time footage (right-click and save) from the HD camera as well.
