Review: I paid a fortune to get it installed at the original new car dealership from a professional. It doesn’t work at all and it’s very complicated to install. I’ve asked for money back, but I haven’t heard anything yet. Avoid avoid avoid.
Review: First, thank you to everyone who adds comment reviews; as a consumer, I find them very helpful. The sensors have been installed for over a week and have performed as listed. I'm giving it a 5-star rating due to the inexpensive cost of the product. As many other reviewers commented on the alarm sensor it can be annoying with the beeping due to heavy traffic. I will probably do what others have done by disconnecting the alarm (the nice part is you can unplug the alarm without sniping the wires). I installed it on my 2007 Jeep Grand Cherokee Limited and found that I didn't need the sensor brackets as the rear bumper was already at a 20-degree angle. The system I found very easy to install. However, patience is required. Plan on about 4 to 5 hours to install, depending on how anal you are about making it look factory installed. Helpful accessories I found to make the installation easier, spend the extra $20 and purchase the Fuse Adapter, T Tap Wire Connectors, and molding tool remover.

Works well, however in 2018 malibu brake and blinker share the same wire, resulting in beeps when passed at stop light. Going to use a nc relay controlled by the brake to disable the buzzer when the brake is pushed.
