Title: Great dash cam/smartrear-view mirror for the price
Rating: 5.0 out of 5 stars
Date: March 26, 2020
Review: This product offers a multitude of features at an affordable price point. It serves as a dash cam, rear camera, backup camera, GPS speedometer, and compass, providing comprehensive functionality. Installation is quick and straightforward, and the large screen makes navigation and viewing recordings effortless. The included 32GB Mini SD Card is a nice touch, though I recommend upgrading to a 64GB card for optimal performance. While there are some minor drawbacks such as firmware issues and glare in certain lighting conditions, overall, this product is highly recommended.

Title: Great wide, clear view.
Rating: 5.0 out of 5 stars
Date: March 24, 2024
Review: This dash cam provides a wide and clear view, particularly useful for vehicles with narrow rear windows. Installation is straightforward using the cigarette lighter power port, although a more permanent wiring solution may be preferable. The picture quality is excellent, comparable to an expensive TV. However, glare from sunlight or headlights can sometimes hinder visibility. Adjusting the angle of the viewing screen may help mitigate this issue. Overall, this product offers great value for money.

Title: WOLFBOX G840S 12“ Mirror DashCam Backup Camera works as advertised
Rating: 4.0 out of 5 stars
Date: August 8, 2022
Review: Installed in a 2019 Jeep Wrangler, this dash cam serves as a supplement to the small side mirrors, providing enhanced visibility. Installation was straightforward, with the rear accessory plug used for power. The unit records well and offers clear visibility both during the day and night. While the GPS unit is somewhat spotty, the overall functionality of the dash cam is satisfactory. The touch screen sensitivity and scrolling features could be improved, but these minor issues do not detract significantly from the product's value. Overall, a solid choice at its price point.
