Works great!
Love these horns. Not extremely loud but definitely louder than stock. Longevity has yet to be seen but they have been installed for over a month and no issues so far.

Sounds like regular horn
They advertise this horn as train horn. I knew without actual powered air behind it it would not be that loud. But tried it anyway. It does not sound any bit louder than a stock horn. Total waste of time.

Good but not great.
Pretty loud. Louder than my stock corn but not as loud as I hoped for. I like it. I don’t love it.

Not a Train horn
Was hoping for train horns as it had advertised and ended up with something that sounds like a standard pickup truck horn, that being said it's louder than the stock horn on my motorcycle..... so I wired all 3 up and let er ride. Loud enough that cars will hear it before smearing me on the road so I can't complain

Don't do it, they AREN'T loud.
The horn once installed, is not loud at all. They aren't even as loud as the original horn. Got these as a gift for my bf,very sad that they weren't up to par.

Chrome looks good on my motorcycle.
Looks good and works like it should. Hope I won’t need another one anytime soon. But I will buy again.

Not loud
Was supposed to be a really loud horn but is not. I didn't returned because I needed a horn for my car. But is not what they claim to be

Not even a close to a train horn, also not even close ti 300db Just a normal car horn in cheap fragile plastic casing

Yes, very good in all respects. It should attract the attention of other boat owners when I am anchored. I was nearly run down by a cray boat once, the skipper was being inattentive.

One horn worked for only 3 blasts, the other one is more like 30db not 300. Removed from car and thrown in the bin which is all it’s worth.
