I installed this on
Audi A4

Review
I got this installed on the recommendation of my Audi SE. He said this is cheaper than the Audit car camera and has better features. I only had to use it once when another car collided into my front left bumper in the carpark and retrieval of footage and forwarding it to the insurance rep was a breeze. Image was clear and phone app was easy to use. It was a key factor toward getting 100% Liability claim against the other party.

What I like
Clear and well segmented video recordings for easy retrieval.

What I do not like
So far so good
