Not bad if it works well. A good alternative for car cameras.
The pro of using this over the in car camera is that no need to retrieve/transfer the video footage from your in car camera, since you can just submit from your smartphone. More importantly it's free and also no cumbersome installation. I think this is a must for all drivers, who do not have a in car camera installed. Do note that the app will only be launched this Friday, and available for both iOS and Android.
Now the thing is, where can I find a good bracket to mount onto the windscreen?
