I ordered the DDPai M6 Plus from an eBay seller on 7/31. I immediately got email from the sellers. I also ordered the polarizing filter (just in case I need it) and the hardwire kit designed for the camera. (Also sold on eBay). I got the whole kit for $137 US. The camera and filter are in transit. The hardwire kit has not yet shipped.
I'm a first time dash cam buyer. I did a lot of research. I probably watched 20 of Techmoan's reviews and at least that many of Andrew's as well as reading a great deal about dash cams in general including hundreds of reviews on Amazon. (What a snake pit that is!) As I learned more about dash cams, I settled on a few requirements. I wanted excellent video, acceptable audio and stealth. I really didn't care about all the fancy doodads like collision warning and lane departure warning. My car already has those. I don't need to know about traffic cameras or speed traps because I'm old. We old people tend to drive slower. (I haven't had a ticket since 1979.)
Since I have zero experience with dash cams, I thought my input might be useful. I liked the idea of a smartphone app and really didn't want a screen. Why would you want to look at what your cam is seeing when you're seeing the same thing? Isn't that what reviewing the video is for? Besides screens add to the bulkiness of the camera and increase the number of things that can go wrong.
I considered a number of other cameras, including the Rexing V1, the Toguard stealth camera, The KDLinks X1, the ZeroEdge 2.4 and the Thinkware H100. I noticed that as the price goes up so do the features I didn't care about. So I decided I wanted a quality camera without a lot of extras. Hopefully I made the right choice.
I bought the camera not because Techmoan liked it, but because the videos were crystal clear and the night video was superior to anything else I had seen. Since the whole point of a camera is to capture evidence that's usable in court, this seemed like the number one consideration to me. I also bought it because of the magnetic mount. The idea of being able to easily remove the camera and slip it in my pocket when I'm in a shady area was appealing to me. I was a little leery about the battery, but the specs seem to be acceptable so I bought it anyway. I live in Texas, but park under a carport, so the camera will only be subjected to extreme heat for brief periods of time. The highest temperature it should ever see would be around 60 degrees celsius.
I like the profile of the camera. It should hide well behind the rear view mirror and not be very visible from the front or side, which was important to me. I'm still trying to decide how to wire it. I don't think I really care about the parking mode, but OTOH it might be a nice to have feature. (I'm retired, so I don't get out much except for trips, and my only parking would be in store parking lots (grocery, hardware, gym, etc.) I don't care about time lapse photos of my garage door, so I'll probably remove the camera when I'm at home and reattach it when I go somewhere.
After it's installed and I've used it some, I'll start a thread on my experiences with it.
