Example Input: Just used this on a 700 mile trip everything was going good. If I saved a clip I could pull it up on memory no problem. Night time came and noticed it didn't switch to night mode on its own you have to manually do it in the settings, no big deal. Problem is there's a finger smudge on the inside of my lens that only shows up at night. Then I get home plug the camera in to my laptop and no files? Take the sd card out and put in to my card reader and nothing. I will get a replacement and update my review..
Example Output: negative
