Not sure about the quality of this kit but the price seems to be great. It was $249 according to the site so pretty good discount there. Maybe even more saving if you can or know how to install it yourself :P

It's a step in the right direction, and not Supercheap's fault but 720p isn't really cutting it for a modern dash cam. Unfortunately 1080p dual cams still cost a lot more ($300-500 for decent ones), 720p is better than nothing but just not good enough today IMO.
Alternatively, 2 x G1W-CB for ~$110 would be superior quality but more hassle.
