I ordered one this week too. I ultimately probably want something better, but I just wanted to get something installed that would be easy. Look good and work. I really just wanted something for the day to day driving just in case.
I have read a lot of mixed reviews about the quality of the image, etc. So I wish they used better cameras but for ease and clean install its hard to beat.
I decided it is better than nothing. I would like to go with the Viofo with wide view inside and extra telephoto out, but then you have no option for rear cam, because it only allows 3 channels, and you will have multiple cams in the windshield at a much higher cost.
I will probably have a go pro mounted somewhere anyway for travel etc, when hitting the trails.
