I had a Xiaomi that was really good. However, when the battery died, it was difficult to replace and it constantly lost its settings...
I bought this one thinking it would be better since it's more expensive.
Another camera that constantly loses its settings and resets to default settings, and you have to set it up again and again...
As a camera, it's good, but even cheaper ones are just fine. However, the problem I described is annoying and I believe they could have had a battery that can be easily replaced to avoid this specific issue.

I have not tried any other, but I am very satisfied with this one.
It is permanently installed on the windshield, it operates whenever the car operates through the charger in the cigarette lighter.
Good video quality, okay at night, not as good, but acceptable to me.
With a 128GB microSD memory card, it records for about 24 hours. The files play easily on a computer and mobile phone.
It was a great opportunity at 109 euros!!! (purchase in March 2021)

I have it for about ten days now and I tried to return it from the second day of its operation (which was not possible from the dealership's side) ... through the store where I bought it back in Kenwood Greece.
It has many disadvantages regarding its operating system, for example, the parking monitor requires continuous power supply from the battery to function... 24 hours a day.
It is excessively sensitive, you can't adjust it... without a delay, resulting in having to manually turn it off and as soon as you close the door, the device starts recording in a loop until you get back into the car in one, two, three, or 24 hours, so you have to re-enter.
Also, a problem with its operating system is that as soon as you hold it in your hand to operate it for any video you need outside the car, it does not work outside the base.
In my device, the battery indicator has never reached full in the past 10 days, it always stays in the middle.
Also, what bothered me is that it came to me without a manual in Greek
