These are the second lot I purchased. Picture quality is good. One minor hiccup is the connection point between the GPS/Charging module and the camera need to clean up; I suspect a bit of dirt or oil, which affects the charging. Otherwise, everything looks great.
The product is bad!!!, constantly stops working, takes pictures unnecessarily, turns off and turns on by itself, the camera does not delete old recordings and every two days I have to reset the memory card.
