I have the ddpai m6+. It's a good camera. For the price it is the best, but it has one serious drawback if it is of any concern. I only found out AFTER I bought it that ddPAI is owned by Huawei... which is a Chinese company with ties to the military. And Huawei is known for nefarious software activity. But still their dash cams get raves from those who don't care.
For $106 it is a good price. I might try to find a different one, just due to the Huawei ties.
But on the good side, it has a swivel magnetic base and a wi-fi viewing app. Plus parking mode, which after 5 minutes captures 1 frame per seconds. It also has a remote button that you can place anywhere, when you push it, it will capture high quality still shots diretly to your phone.
The swivel base only swivels 30 degrees, but if you orient it just right on the windshield, you are able to twist it far enough to catch the edge of the driver's window. This type of mount is the best I could find to work around the over-abundance of black dot shading Honda has in the top of the window.
At the moment, I continue to use it... but I have blocked the app from Location, and Cell. And I work around it for the time being. They are replacing it with the M4+ which is black.
Here is the Amazon Link.
