Just found an SD card, albeit not a high speed one, just so i could have a play with it.
First impressions........pretty damn ropey to be honest, but i'm gonna be more critical than most 'cos i spend all day looking at HD monitors at work.
720 was certainly noticably worse than 1080 so that won't get used, i never even bothered trying the VGA setting.
There's not many menus to go through, just adjust them one at a time and you can't go too wrong, unless you press the system reset button, then everything is displayed in Chinese, which is fine, if you're Chinese, but i am not.
If you do this perchance, press the menu button and it's the 2nd menu down that changes it back.
I noticed if you take a still of a paused video it makes it even worse so i've not bothered showing one on here yet, until i've tried the correct card out.
It didn't seem to do too much when i plugged the unit into the USB on my laptop, it didn't want to recognise it at all, but that's no big deal.
I took the card out, and inserted it into my laptop instead and it asked me if i wanted to download media, which it did straight away, then you can just play the file(s).
You need to format the card before using it too, which is on one of the menus.
I'll post more when it's been tried out properly, but for under a tenner i was hardly expecting 8k quality.
It is what it is.......cheap and cheerful, and is really designed to see vehicles misbehaving rather than the drivers eyes, so it is more than capable of doing the job.
