I have this one, which is similar to the one you cited:

Here's my review on Amazon:
The camera itself works fine. The battery lasts only 2.5 hours, but picture quality is good. The only complaint I have, and it's pretty major one, is the mounting hole thread is plastic and on mine it has already been stripped. I went over a speed bump at 30 km/h and the camera just 'popped' right off the mount and crashing and rolling over a few times on the pavement. The first time it happened I thought that it wasn't on tight enough, but the second time it happened less than a week later I knew the flaw lay somewhere else, like in the manufacturer/design. To its credit, even after two hard tumbles the camera still works. I was lucky it did not land on the lens cover. I've had it for only three weeks, and I was not tough at all on the equipment.
So if you're thinking of buying this, be aware of that. this is a pretty major flaw, and if you strip the thread it renders the unit pretty useless for any application. I was able to mount it onto my helmet using some zip ties and make it work as a helmet cam. If you are less handy you might want to stay away from this camera.
I was/am contemplating getting the same camera to work as a rear-facing one, despite the flaw. The main reason I am considering it is the battery. I can get 2.5+ hours of use during the warmer months, which is more than what most of the GoPro-style ones give (usually under 90 min). Even in -10*C or colder I can usually get 60+ minutes, which covers my commute. I'd charge it at work, of course.
I bought one last week which I fully charged, but after 20 minutes in -5*C it died.
For the time being I am just using one of my regular hand-held waterproof cameras mounted on the seat post to do the job. Only issue is that it only records 30 minutes of video at a time, so it requires me to turn it on again after 30 minutes.
