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.

this horn is sweet! The Mazda in which I installed it came with a stock horn that couldnt frighten a squirrell. Besides the small space I had to work with, installation was a piece of cake. One suggestion, make sure you have a 20-amp circuit. The first time I layed on the horn for a driver who pulled out in front of me I fried my 15 amp fuse.

I bought this for my motorcycle, since the stock horn sounds like something that belongs on a child's tricycle. The toughest part of the installation is mounting it so that compression of the front struts doesn't hit the horn. I had to use two metal mounts (doubled together for strength) that came with stock horns I had lying around. Once I bent them at 90 degree angles, I was able to mount the horn using the bolt and nut that comes with the Wolo, as well as the mount bolt on the stock horn. Wiring is pretty easy and straightforward. I just re-drew the diagram so that I could read it without a magnifying glass. Keep in mind that the instructions tell you that it doesn't matter which wire on the Wolo goes to ground or the battery, but it definitely does matter. When I first tried the horn it sounded like a dying moose; but when I switched the wires around it roared to life and scared the hell out of me. You will definitely be heard out there on the road!

I use this horn on several motorcycles. It is compact enough to fit well, and loud enough for its size.

Those who want a louder or lower pitch horn will have to look at a larger, more expensive horn.

However, since they have outsourced their production to China, the quality and reliability have gone down the toilet. The last one I bought was a terrible disappointment, both in quality of construction, sound and longevity.

The chrome plated model is a joke, now. Mine turned green in a couple months in a damp environment. I ride to work, so it sits out in the weather in the parking lot.

Too bad. I really like my earlier Italian ones.

I really like the horn, and the great sound will make it much safer on my bike now. However, I must say that I was disappointed when it arrived and I found to safely install it on my Harley, I need to go out an purchase additional hardware. The product futures state "One-piece design requires no hoses and installs in minutes by simply transferring the factory horn wires to the compressor... The Bad Boy is compact in size to fit any car, truck, motorcycle and any 12 volt vehicle". The package goes further and states "Installs in minutes without special tools...complete with all mounting hardware". Not true if you plan to mount it on a motorcycle. The instructions require that you use a relay (provided), run additional wiring from the battery and the horn, and install an in line fuse (all not included) before it would work without possibly damaging the bikes electrical system. The additional requirement, cost and effort to install almost led me to send it back. However, I decided to keep it and despite the misleading advertising and additional cost I am glad I kept it because it sounds great and is LOUD!

I have had this horn on my Triumph Bonneville America for about a year. It is extremely loud and attracts alot of attention. It was easy to install and has proved to be very reliable.

Mounted this on my scooter to replace the "meep meep" factory horn. Wanted to scare/wake up lane-merging car drivers. Only had it a couple of weeks, so I can't vouch for it's durability yet.

What it is/does:
-Louder than what you might call a "normal" car horn. I'd say 2x louder or a little less is fair. Meets my expectations/needs for sure.
-It hurts your ears when you're next to it and I can feel the air pressure/sound waves hit my ankles near where it is mounted. So it's legit.
-Fairly instant-on, despite what another review said about a delay
-Somewhat big- the service guys had to get really creative finding a space to mount it, but they did.
-Meets my expectations for getting car's attention. For sure.
- Great value

What it isn't/doesn't do:
- Won't make you sound like a semi or huge truck. It's higher-pitched, about like a car horn. Think if a hand-held airhorn and a truck air horn had a child. It's this. Maybe leaning towards hand-held, but it doesn't sound embarassing.
- Be as loud as a semi/huge truck. Its plenty loud. A big improvement, louder and more "piercing" than a car horn. But it's not train horn. It's not going to make your ears bleed. Think about the effect you want.

Bottom Line:
- A great and affordable upgrade to a car horn or for scooters/cycles. Will get driver's attention. Maybe not if they have the stereo absolutely cranked. Plenty loud, but not an earth-shattering train horn. Won't make you sound like a Mack truck.

The End.

Update: Rode with this mounted to the underside (covered) of my scooter for an entire season (May-December). Some rain, some temperatures below 30 degrees F. Absolutely no problems to this point. Performs consistently and well in a variety of conditions.

Update: 2 years on, this horn is still working perfectly. Stored during winters.
