Recently bought a $50 "5k" action cam and it was the first chinkshit product ever that truly betrayed my expectations. Had great product design, nice touchscreen on the back, front screen, decent UI and settings, easy to use, everything was great. Only thing they skimped out on was the camera. It was poor quality 720p with no autofocus at fixed 30fps upscaled potentially to 5k, or saved as 120fps, but still 30fps. I have no idea why they'd make everything good and then fuck the camera, the one part that actually matters. I had free returns on it, and returned it. At one point I'd bought an ultra mini action/borehole cam literally for $2, and that thing had almost comparable video quality to the cheapo "5k" camera.
