Absolutely five stars for this dashcam. I have them in every vehicle I own and they perform flawlessly. The video files are easily accessed via smart phone, computer or laptop. The video files function perfectly on both Linux and Windows operating systems that I use. I use the OEM SD cards as well as Sandisk, Kootion, SuperPro and generic cards; all function perfectly in these cameras. I'm going to attach pictures to this review, but please note they were pulled as a screenshot from the video so there is some quality loss from that and my windows are always dirty which also takes away some of the picture quality. Believe me, the video quality is much better than I provide with the pictures attached to this review.
