Simple to install and...yikes...VERY, VERY LOUD!

I bought two of these for my motorcycle. The last bike I had I installed a much more expensive metal horn which was much louder than these. You get what you pay for. I’d like them to be a bit louder but they’re ok. You do need one pump per horn unfortunately, but ok, I can live with it. Fyi, for those wanting two horns with different pitch, if you unscrew the back of the horn, drill a hole in the center and thread in a 3/4” machine screw with a thread protector on the tip, you can use that to tune the horn and have two horns distinctly different in pitch instead of both with the same note.

Good and loud horn it definitely get people's attention. I have it mounted on my ebike they don't expect a bike to have such a little horn. It's needed with the way people drive around here

I've had this hooked up to my truck (under the hood). In just a couple months I've found the horn to sound weak. I had to recently disconnect & remove it and then hook up my original horn. The air pump motor seems reasonably built but the horn itself is very cheap and feels like a toy horn.

Interstate Left Lane Campers, Sleeping at a Red Light/Stop Sign, Generally Choking Traffic By Going 20mph Under the Limit... you are getting this horn blown at you! I watched a lot of videos on Truck/Train horns, and this one, surprisingly came in very loud. For the price, I couldn't pass it up! Mounted the pump next to the battery, running off a 15A relay. Mounted the horn under the bumper frame support on my F150. Its VERY LOUD!! Its gotten the attention of EVERYONE its needed too so far! I have had it installed for a few months so far, and unfortunately, I have had to use it way more than I want too. I have about 5ft hose from the pump to the horn and it takes about 1s or less to light up when I hit the horn. Momentary honks from truck factory horn when setting alarm, do not generally cause this horn to light up, but if the alarm goes off, look out! Its LOUD... especially in the carport! For the price, you cannot beat it!! Recommended.

It’s cheap plastic and cheap price so dont go cranking on it. The thing is LOUD for being a small 12v on demand air horn. Got a nice little relay kit with a separate button all wired up in the truck and it works great. Be aware the thing pulls 26A so plan accordingly.

I installed this unit in my Honda Accord for that added attention I want when a horn blast is necessary. The Honda Accord has two OEM horns. I replaced one with this airhorn. Three issues of note. (1) The first product arrived without any installation hardware. AMAZON was quick to provide a replacement. (2) the quality of the horn is spotty at best, with the chromed surface rough in some spots - only noticeable when you have horns two together for comparison. But, who cares. I placed the horn behind the grill work where only a mechanic will see it. (3) the horn requires a minimum of a 15 AMP circuit to operate. The Accord circuitry is 10 AMP. I simply moved a 15 AMP fuse into the circuit. Other than that it works and it is loud. I will appear to be a big truck, with a car's body in the rear view mirror.
