Integrating a dashcam into a rear-view mirror is a very sensible idea but it also comes with some unexpected issues, and these unfortunately mean that this particular camera is not suitable for me.
This isn't a bad camera though and may actually be exactly what some people are looking for. It's simple to use, forgoes the complications of G-Sensors and GPS but incorporates the essential car DVR features such as looping video and auto-start/stop (providing your 12V socket powers down when the engine does).
Perhaps the best feature about this camera though is it's price. When I bought mine I paid just £36 including delivery. Unfortunately if you are in the UK, then you'll find that this isn't suitable for your car (watch the video to see the reasons why). For readers in other countries (who greatly outnumber my UK viewers) the current price at the time of writing is $60 USD, $57 AUD, or €45
You can CLICK HERE if you want to buy one (this is where I bought mine). Note that this camera seems to be named the X888B.
P.S. If you really want to download some files taken with this camera I've uploaded some here, two have been converted into MP4s (so I could edit them) and one is untouched - but if I were you I wouldn't bother because the youtube video is a very accurate representation of the video quality produced by this camera.
