This dash camera set is all plastic but feels well made and well designed for daily use, with simple controls and a rotating rear. A standard sized 'rectangular brick' design, it works as intended with buttons and ports for power and video. Each piece is plastic but they are well made with a good set of lens on all the cameras. The design style of this dashcam is definitely on the uglier side, but safety first, and is a good visible deterrant.\n\nThe resolution at 1080p is clear and sharp, and most will be content with the footage in both sunny and dark conditions. The front is 4K and is definitely 4K, though there is some odd blurring for text, but plates are mostly visible when nearby. From afar its still blurry but the cars on the road is easily identifiable by model. The rear and back 1080p cameras are very basic but provide a standard sharp 1080p video from the popular STARVIS sensor.\n\nThe mount is the weakest point of this camera, as it is not as firm and rigid as I would like. It works well enough, but is an eyesore on our van which has a very raked windshield. I tried putting it behind the rear view mirror but it wouldn't provide a good camera angle.\n\nI would recommend getting a fast 60 MB/s or faster Microsd card, so this is usually a SanDisk Ultra or Extreme. I tried using a cheaper Lexar basic MicroSD but the footage kept corrupting with a slow card error. I believe this is because the write speeds could not take writing the 4K and TWO 1080p footage sources.\n\nOverall this is a good simple set for those who want a three channel dash cam and 4K, GPS and WIFI features, a rear camera and a back camera that points at the rear passengers. This is perfect for uber and delivery drivers.
