I bought the Wolfbox G840H 12” rearview mirror a few weeks ago, and I am very happy with the product. I have a camper shell on my pickup, and the rear window on the shell is on the dark side, so it’s hard to see what’s behind me. This solves all of that and works very well. When shopping for this device, I read a lot of reviews for this mirror, along with many other models. One of the complaints I read about that concerned me was if a vehicle behind you had bright lights at night, the view would be distorted from the light bloom, and you wouldn’t be able to see anything. I think that’s false. My mirror has a very clear view at night, and yes, there is a little bit of light saturation from cars or trucks behind me, but it’s a better view than what I see out of my side mirrors without a camera or screen involved. In backup mode, the ability to adjust the view height on the fly is great. Overall, I like it a lot. If I have a complaint, I’d like to see a faster refresh on the picture. What I see is very clear, but it can appear to be a little jerky at times because of the refresh rate of the video, probably from the camera. My wife doesn’t notice this, but I can be picky with electronics.
Update: I thought about the saturation problem where people complained about the bright lights behind them at night oversaturating the camera. On my pickup, I have the camera mounted up high on the camper shell. If someone has the camera down by the license plate, it's probably susceptible to a more direct focus from the headlights behind to oversaturate the camera. Recommendation - mount the camera as high as you can. That might be tricky on a regular car, but it's worth mentioning.
