I thought this mini DVR was too cheap to actually work but I was wrong. It works as expected, even in a hostile environment. I attached it to the drone with no housing or protection to record video from further away than my FPV radio allows. Works great so far, even in extreme cold. A little curiosity: the timestamps of the files are all 0:0:0. This DVR is so small and so cheap that I'm not sure it even has an RTC. And that's okay!
