Bests & Worsts Reviews from Amazon

This is a great horn, hands down. Makes a sound like a Mack truck, and is compact, and easy to install. Just read the instructions. All of the negative feedback thus far is from people who either have no understanding whatsoever of 12v automotive electrical systems, or did not read the simple installation instructions. It took me 20 minutes to install this horn, and I even had to run a new wire back to the place that I decided to mount the horn from the old horn's location. This horn will pay for itself a thousand times over the first time it keeps that Chevy Suburban from running you off the road at night. It's also good for scaring animals and small children, if you happen to be into that kind of thing.
