Review: UPDATE - I LIKE IT NOW even though I reviewed it as a "Dangerously Shoddy Product" - On the very first use it fell apart in my hand and blew the back cover off, hitting my face. Inner membrane is shattered. Now told I cannot return. Updated to three stars because they gave me a prompt refund. Good company, so maybe I got a bad horn. Would still order from them again. UPDATE: I HAVE USED IT FOR A LONG TIME NOW. It is reliable, and has a LOT of life. There is a lot of gas in the cylinder, and I have had no other issues. So, I say I like it, would buy it again, and their customer service was enough to cover a one time broken part. Oh, it is REALLY loud!

POLICE ARE NO HELP (PORTLAND, OR). SO, I'VE STARTED BLASTING HIM WITH THIS AND, TO THE RELIEF OF MY HOUSEHOLD AND NEIGHBORS, DUDE DOES A 180 AND TAKES OFF. IT HAS RESULTED IN HIM COMING AROUND A LOT LESS AND I'M GLAD THAT I WAS ABLE TO DECREASE THE AMOUNT OF FORCE USED SO I DON'T HAVE TO RISK HIM SUING ME FOR BEING TASED OR HOSED DOWN WITH BEAR SPRAY. THIS IS NOT A JOKE. THIS HORN IS LOUDER THAN THE OTHERS! ## Frequently Bought Together - Mainstream Marine Big Ol’ Blowhard Marine-Grade Air Horn, Portable Loud Air Horns for Safety, Emergency Boat Blow Horn Can 16oz, High-Capacity, Can Be Heard 1 Mile Away, Boating Accessories - Shoreline Marine Eco Air Horn - First Alert Fire Extinguisher | Marine Fire Extinguisher, White, FE1A10GR, 1-Pack, 14" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/203089491-16oz-mainstream-marine-big-ol-blowhard-marine-grade-air-horn](https://www.desertcart.hr/products/203089491-16oz-mainstream-marine-big-ol-blowhard-marine-grade-air-horn) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-08*
