Not sure how he mounted the camera in the car exactly, but if it was upright, then there is something wrong with the G sensor on his cam. It's nowhere near 1G vertical. (Y)
Unfortunately not too many tests in the review, didn't even know that it has a battery (which is stated on the box). I suppose it does point out some interesting things though, like the clutter and black 2 sided tape etc.
One hell of a good dashcam, find that once setup just leave in car.
The only problem I have with mine is that it stands out so is easily seen from outside due to the contrast between black paint and white lettering I am going to have to paint it to match the grey colour of my sun visor to stop it showing so easily.
