My wife got this item as a birthday gift for me, and I have nothing but positive things to say about it. Sound quality is really good, and the installation was a breeze. What really stands out though is the video quality. I was almost side-swiped today but was able to avoid it and made it to my destination safely. After connecting the SD card to my computer, I was able to replay the video and see what happened. Even in low light the camera quality was sharp and able to pick up everything that happened.

When I received it everything was in Chinese which was no big deal as the manual gives easy instructions to change the language, but after setting up the Bluetooth, the video was still operating in Chinese. I had to go back to the book to figure out how to change those settings as well. Not a big deal, just a minor one time inconvenience. Since then, it has been an amazing addition to my commute.

One thing to note, format your card before you ride the first time. All my videos were time stamped as 1900-11-01.
*Edit* you have to connect it to the suggested App to get the time stamp synced to your phone.

Ride safe out there, but if something happens, definitely have the Kentfaith dash cam to have proof of the incident.
