I purchased this CHUPAD D501, and it has plenty of issues :
1/ leaking minutes and dozens of seconds, in some video, it leaked more than 1 minutes
2/ random videos time (not always 3min or 5min as configured) some videos record 20 seconds, the next records 1min 30sec ...etc, so it will store many many video files and make it very hard to find a video of a specific time you are looking for.
3/ annoying sound every single time it starts or stops, I removed the beep sound from settings, but this start up /shut down noise won't go !
4/ dash cam not stealth mode because it has chrome surrounding and lens is 100% chrome too
5/ car licence plates cannot be identified while moving, you should be stopped and the other cars should be also stopped to be able to read them
I have to say, the angle is real 170° though which is a plus, and also the night videos are good ! and I've got a partial refund, but still very disapointed, I spent a lot of time looking for the perfect budget dash cam, now I have to find another one
