Bought this dashcam to use in a rental car we drove across country. It was delivered to our hotel in less than 24 hours. We were very impressed with this dashcam. It is very light because it is made of a lightweight plastic, but then it didn't fall off the windshield a single time. The video recording is displayed on the screen for about a minute, and then it darkens so people don't stare at the dashcam while driving. The resolution appears to probably be 2.5K or 1080p, not 4K but good enough in bright light to produce a good image. Nite time video is not great but I think all dashcams struggle to record nite video with headlights. I would guess its frame rate is 30fps and not 60fps in order to produce smaller files. The files are .mov format and saved to the microSD card THAT WAS ALREADY INSTALLED. And this gets to why I took off a star: The directions are terrible. They start with explaining how to install the memory card, and I almost returned the cam because it wasnt in the baggie. I finally noticed a second slot with something in it and ejected and reinserted the card using a paperclip. The open slot must be for the mic for recording video in the car, which is saved on the card as a separate file. You have to remove the card and use an adapter to view files on a computer. I was able to view them on our 4k TV, which is why I think its resolution is 1080p or 2.5k. Its not 4k. The instructions go on and vaguely mention setting the cam up, but I basically started randomly pressing buttons until I found a menu. I did this by using a cell phone charger and a cord in the hotel room. To try and do this in a hot car would have been no fun. Once I got it set up, it was plug and play- automatically turning on when the car was started and power went to the 12v outlet, and off when we shut the car off. We have other dashcams from other manufacturers, and they all have pluses and minuses. But for $50 including delivery, although the resolution isnt very high and the instructions are terrible, I dont think there are many better buys out there. Id probably shop around and pay a little more for my daily driver's dashcam but this did a nice job and will be the one we take when we travel.
