tldr; Budget 4K dual-cam favorite. Some heat issues reported in 4K mode. Better options exist now (A229 Pro).

Best praise vs top criticism for Viofo A129 Pro Duo
“Lol I don't know who those 2 people are, but don't get a no name weird "owl cam". It's basically a crappy camera with zero functions that's whole purpose is to rope you I to a subscription service, rather than your own SD card, or downloading it to your phone. I use a Viofo A129 Pro Duo and it suits all my needs. No monthly subscription. Both cameras are Sony starvis 2, which is just known as the best you can buy, and it's not expensive. Maybe this was an ad for whatever no name camera, bit yeah. Don't buy that lol. You're gonna have a bad time.”
“I just dumped the A129 Pro Duo a a while back. Recording in 4K during the day and the damn thing would overheat and shut down. Got it replaced and the replacement unit did so as well. Support told me to stop recording in 4k to avoid overheating. That is ridiculous if it's a feature of the camera. I am not talking the dog days of summer either.......I'm talking mild 85-90 degree days even when not in direct sunlight (my windshield has a tint strip on it which keeps the camera body out of the sun). It's is even mentioned on the FAQ page for the camera..... https://viofo.com/content/36-viofo-a129-pro-duo-dash-cam-support/ I went to thinkware and even though it cost more, I did not have the same issues.”
