I have AKASO EK7000. To be exact, I have two, one mounted under seat looking back, and, one on handlebars looking forward. Had them for about two years, so, far, no problems and no complains. They each came with two batteries (1050ma). Each battery gave about 1:30-2:00 recording time. I bought replacement (higher power, 1400ma) batteries off
eBay, they give about 2:00-2:30. I have submitted footage to Police, they accepted it and acted upon it. The recording format is .MP4 (a commonly used format), recording is in 15 minute "chunks".
You can see actual un-edited footage at link, below, if that helps, this is at the lower 1080p resolution, 30fps, the camera will do 4K, 25fps.
