Awesome sound, easy to use! If the need arises, I will certainly buy from BossHorn again!

Using it for Evansville Otters baseball games when the Otters hit a home run. Work great, got to use it four times in the first home game.

I can't say enough of how awesome these are. I've throughly enjoyed them since I got them. I've used them at sporting events and even parades. You can't go wrong with buying them

Bosch Train Horn: Quad Air Horn

I love it.Wife not so much lol.Thanks worth the $$$

Absolutely ecstatic, happy happy customer

It’s very loud. I love it. Thank you.👍

I was skeptical when purchasing however after opening packaging and seeing the quality of the product I became reassured that I made a good choice. I installed battery and horns and WOW...these are for real! Very Impressive!!!!

Love this this thing great for kids games when you want to embarrass them or just be obnoxious plus freaking people out at bus stops is hilarious

Our boss was looking for a loud horn to use at a company event to get everyone's attention. BOY, DOES THIS DO THE JOB !!!! (we purchased the Milwaukee Train Air Horn M18: Dual - BossHorn × 1 Tool only / Red). Loud is an understatement!!!! I cant imagine what the 4 horn sounds like!! Our property is 14 acres of open space. The sound reaches every corner of the property. Well made. Easy to assemble (all you have to do is screw on the horns, attached the battery and press the trigger) BOOM!!! Btw, THE BOSS LOVES IT !!

This has truly helped me in my day to day shenanigans! Future's looking bright 😎

This thing is amazing, I scared the $!+@ outta my kids the first three minutes I had it. Will be amazing for our Lacrosse tournaments this spring!!! Shipping was spot on and everything arrived as promised.

Love the Boss Horn. Great sound and LOUD! Impressed my friends at football tailgate, although they thought I was a little crazy (;

Excellent . Love it. Use it for my kids sports.

I shipped mine back as it was not a dewalt gun. A new gun is to be arriving this week.
