I bought this dashcam based on positive experiences from friends who have had it in their vehicle for a long time. Installation was very easy (for now). I now have it connected to a power bank via USB. Of course, you can also operate it using the cigarette lighter while driving, but since it doesn't provide electricity at night, this is not possible with the night-time parking control. I will have the dash cam connected to the power grid so that the dash cam can also be supplied with power at night. The picture quality and the sound quality are impeccable from what I can judge over the last 2 days and nights. The menu navigation is simple and easy to understand even for non-technical people like me. The only thing I could complain about would be that you can't easily control the dashcam via an app. You just have to attach the cam to the PC or remove the memory card. But hanging the cam on the PC to watch the films in large format (which you could also do via the small display on the cam) is really simple and easy. I'm glad I chose this cam and would do so again and again. Absolute purchase recommendation. Of course, I hope that I never need the recordings for an emergency, but I just drive with the camera more calmly so that I am prepared for a dispute.
