I have three different brands and I like them all. My favorite is a permanent mount blackvue single channel unit that I use in my daily driver. Great quality video and playback. Higher price point but a very robust unit.

I also have a Garmin 57 that the DW has in her car. A great unit easy to use. Very small compact unit. Garmin tries to get you to sign up for some additional features like storage but not required.

I also have a Rove which is a great value for a dashcam from Amazon. Not as robust with the features as the other two but a solid unit at an attractive price point. I use this in my coach because the suction cup mount works great for that application and I needed a unit I could put up and down on the windshield.

Lots of choices out there.
