I ordered this product as a cheap replacement for my OEM horn after it broke. Seeking a bigger footprint for a small dollar amount, I decided on this product. First off, let me say how sturdy the build quality is. The compressor, the horns (even being plastic feel well made), and the mounting parts. I am not worried about any part of this breaking under normal driving conditions. Second, this horn is loud. Very VERY close to the advertised 135db, which is exactly what I was looking for. Even without a full sized air compressor, this product packs quite a punch. It is a very good choice for those looking for a powerful horn, but not wanting to pay for a full sized air compressor. Lastly, the ease of installation really made this product a full 5 stars for me. Even if you have minimal electrical/mechanical experience, installation is a breeze and can be done in as little at 15 minutes. Overall, I am VERY satisfied with this particular horn package and will probably be reordering this same one as a replacement in the event that mine does break.

A jet engine at take off is 140 decibels this it 135 so its pretty loud. One of the horns was cracked when i got it but it doesn't effect use, compressor seems high quality tho. Very easy to wire if you know what your doing with the relay, the directions were no help. YouTube will probably be your best friend if you need a walk thru. It fit well in my 2000 jeep xj compressor on front of the air box and horns behind. It comes with enough tube to face them forwards, very limited with the mounting points but just as long as they dont bounce around to much they should be alright. Nice for when people cut you off.

For the money this thing works great. Nice and loud. Loud enough to make you plug your ears if you’re right in front of it. I have had expensive “train horns” before. These aren’t that loud. But for the dollars spent, you won’t be disappointed. Made of pretty thin plastic. I got mine mounted with the hose provided but you might need more. Also some basic understanding of 12v wiring might help. Came with most parts needed. Everything came intact with nothing broken or missing. I wired it to a second horn switch. Over all I am beyond satisfied with what I got for the money spent.

Product is OK. The little air compressor seems well-made. The airhorns themselves seem a little cheaper, but I mean they don’t have to be like super strong or anything I guess. But my issue is they do not work when it is really really cold outside. I live in northern Michigan and on days when it’s around 0°F all I get is a really high pitch squeal from the horn’s. I thought they had come unhooked, or the air hose might’ve been leaking. But that was not the case it just didn’t work in the cold. But it warmed back up to 45° a couple days ago and they started working again. The product is very loud not quite as loud as I was hoping for but definitely louder than the factory horn. So bottom line if you live somewhere where it’s going to be very cold quite often this might not be the product for you. But if you live somewhere that can stay 45° or above they probably would be just fine.

This thing is a toy that sounds like the first note of the Mexican ice cream trucks song. It's cheap and definitely not loud. My regular horn in my Grand Marquis has more authority than this thing. The sound is embarrassing really and every time I pressed the lock button on my keyfob I'd have to hear it so I decided to return it. Turns out the return window closed yesterday! I'm just gonna throw it in the trash.Installation was whatever, it's not super simple and if you don't have a little knowledge on it, the directions will leave you with more questions than answers.

Super pleased with this purchase. Yes, the horns themselves are plastic which depending on how you look at it is either a plus or a negative. Personally, I'd rather not have to deal with the inevitable rust on metal horns so this is a positive to me.The compressor is of good quality and the included wiring harness complete with relays is handy. The end result is a satisfying Ferrari sound which is exactly what I wanted for my motorcycle.For those saying that these horns are not loud or don't sound right there's a higher than average chance they didn't wire them up properly using the included relay. Trying to use a horn like this with a drastically higher amp draw versus the stock horns on most vehicles will indeed yield poor results - you MUST use the relay to ensure the compressor is getting proper amperage.Happy with the purchase and would order again.

I have bought many other horns on Amazon and this one by far has lasted the longest, is the loudest, acually sounds like a train, and comes with all the wiring you will need. Includes easy plug and play fuse and relay. And this one I have taken on long road trips way up north in Canada and as I'm driving in icy freezing rain, snow, ice the horn still works.. this is 100% the best horn you can buy on Amazon for how cheap it is no doubt about it! This is a true review and I was not paid to say this.. it really is just an Amazing horn for the money.The horn is on a 2006 ford escape and is loud asf exactly like a train.

I like the loudness of the horn. I had to disassemble part of the front of my truck to install it. The grill. Part of the front body molding. And had to remove the headlight assembly. Then I realized there was no hose shipped with the unit. Luckily, I found some hose to complete the job. Otherwise, I would have had to reassemble everything to go get hose. NOT HAPPY!!Also, the box it came in was damaged when it arrived but, like so many others have already said, what can I expect for the price? I'll tell you what I would expect. All the parts being in the box.
