Otherwise, to make concise:
The +
In case of incident, you will have a "proof" of course not recognized by the courts, but difficult to contest
You tend to moderate your behavior (knowing you filmed)
If your mechanic m **** with your car during his interviews, you'll know ^^
She films the outside and inside the vehicle
Accepts without problems the 64GB cards

Not always easy to position correctly
Taking the GPS is VERY weak (I knew I still botched)
Unable to read a plate if the car is "stable" and less than 10m
The sound is pretty bad
Lighting "night" in the cabin is pretty bad
HD HD has the name
Unable to read / save videos other than the supplied software (fortunately still available on the memory card)
For the manual (Originally mine was configured in Chinese I think. I can not tell you the joy to navigate the menus) it will search the net
the buttons are VERY wrong place
In short, the product is very nice, but far from perfect. Is remains that that price, it's hard to beat (even a year later I still have not found a clean competitor on time to buy a second camera)
Frankly it deserves its three stars, but clearly not deserve a fourth.
If you are still unsure about the usefulness of such a camera, invest fifty euro in it is frankly the shot
/! \ I saw that Amazon offers an SD card enclosed with this camera offers. It uses microSD cards rather conventional SD!
