Very easy installation and high quality video. A great buy for the money.
Not bad but just a bit muffled
Average build quality. The sound is a bit muffled so I would not use it for music but it works ok for audio books in the car.
Figured out most of the features within the first hour. Easy to use and does and excellent job. inside and outside of car. I'm not sure how the motion detector works yet but I set it up. I highly recommend this product.
