It was easy to install - put it under the back of the car and run the wire to the reverse light. Running or driving my golf cart behind the car if it sounds like I'm backing up. Mixed reactions - some know the car is reversing - some think it's a signal to position yourself directly behind the car, others see it as a warning to see if they can get through before the car leaves space leaves. Overall - I would take another one, it's a good idea.
