Read my post below (from August). Nothing has changed. Rostra system is working well with no issues. It has survived the winter of snow and ice build up and works just as day one. I like this system because the 2 sensors mount behind the bumper fascia where they do not get damaged. The piezo speaker and 3 LED's are mounted by the rear cargo light (so you see it when you turn your head to back up). It kept my wife from backing into a "low" pole so it has already paid for itself. The dealer who put it in only charged $25 bucks more (installed) than I could buy it for from Rostra. He also gives lifetime parts and labor warranty so it was worth it to me. The
ebay systems I saw only worked to a distance of 1.5 meters (about 5 feet?) according to the instructions and pictures with the LED display. The Rostra starts at about 12-15 feet and gives you solid tone and red LED at 4- 5 feet. It actually looked real easy to hook up but again $25 lifetime warranty worked for me.
