"I rarely write a product review, but I'm so pleased with this product I felt compelled to do so.
I'm a retired Radio Frequency Engineer, and I'm pretty amazed at how well this product works. I tow a very large popup camper and can't see anything behind me. I bought the license plate system and mounted it directly to the fiberglass back end of the trailor near the center. I'm pulling power from a running light so that the system is on full time. I also have the gradient feature.
My receiver is suction cupped to the windshield. I'm using a 7" monitor which is sufficient.
When passing someone, I could never see when it was clear to pull over back to the right lane. This system with the gradient lines shows me when it's clear. Before I had it, I had to guess. It also helps greatly when I have to back the camper into a site. My truck has a backup camera but it's obscured by the trailor. I can see where to stop backing with the Tadi Bros. system and the gradient lines.
I get some flickering of the image, but not bad enough to be concerned. Consider that the signal is being transmitted through 19 feet of fiberglass and aluminum to a dash mounted receiver in my truck. Pretty amazing that it works at all.
I can see when someone is tailgating and when someone is approaching to pass. That's a lot of peace of mind.
This is a great product. I'd do it again in a heartbeat."
