I've one, had it since Dec-ish OK in sumer but lower light performance can be a bit hit or miss, if it had a higher frame rate then winter performance would be better. Quite a wide lens which is good in some respects but can have some issues focusing on the very edges and does distort the view a bit as to how close someone is on the sides. Having a bit of bike in view helps set the reference for this however. With where mine is mounted it is very unlikely to make out the occupants of a car, this is usually due to closing speed and frame rate plus not helped by windscreen reflection.
Battery life OK, I bought a spare battery at the time. I get about 3 hours or so out of a battery, there's no charge indication but I tend to swap it out after about that time.
Internal clock is set using a text file on the card, clock time resets if you take the battery out. Not ideal on a ride so I use a power bank to power the camera whilst I swap out the battery.
It overwrites the data on the card in a loop, duration video segments can be set, I think mine are set to 3mins which gives about 534MB file. Sometimes the loop overwrite stops working and the camera stops working because the SD card is full. I run a 128GB card in mine so this happens not very often but I have had it happen 3 times so far.
There's a very small time gap between files, sub-1 second but you can get unlucky and have an incident happen across that gap (I had that once so far)
Audio recording on it varies, on one bike you can hear my breathing on another you can hear my brakes operating but any verbal is hard to hear, this is mostly down to camera mounting location and wind noise.
The mount provided for the bike is quite chunky, I printed my own ones which work quite well and always ensure the camera is the right way up without a tilt. Helmet mounting is using a big chunk of velcro I am sure it works but not for me, it would be useful to see where I am looking which the helmet mounting helps with.
This is a rebranded old camera, i.e. the guts in a new case. It's based on the SJ2000 camera here's a review of it

In terms of a £33 camera it is good for the price IMHO, any more than that and it is less good value I think. I like it's low profile appearance.
In terms of real life usage to report drivers, I think it does it's job. Reporting has a better hit rate at the moment, almost all reports I have done have resulted in some action (mostly course or conditional offer with one prosecution) but it takes a while to do, I figure about 30 mins per report once you have copied the video off the camera (I usually identify the clip and then copy the before and after clips) then spliced the clips together and cut to give a movie with 2mins pre-post incident. You then need to file the Police report with Essex Police online and upload the video to Essex Extra Eyes dropbox account.. a week ago a 2 hour ride took 3 hours after to report the drivers in it - so it depends on the nature of the incident.
