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

Size is big, loud, doesn’t leak, lasts long, and performs as expected.

Can feels half full ea purchase. Ive owned 3. Top horn is kinda fragile so handle carefully .But over all a great can horn. Pricey

Great for pranks and being obnoxious

Was very excited to get this for my camp, and I squeezed it for the very first time, the back blew off and the little plastic circle to echo the sound shattered. FIRST SQUEEZE. We had to make shift rig it back together and it now just sounds like a normal airhornEDIT It no longer worked. That fluke airhorn sound stopped and all that continued out was the leaking air. Terrible product, do not purchase

It's a good horn. I was hoping it would have a more trumpet sound, but it will still get someone's attention.

I like that it’s loud. I bought it for the wrong reason. But it works. My neighbors make a lot of noise that live over me. So I get blow my horn when they make noise. And they quite down. Sorry but not sorry 😈

This unit is much louder the the smaller hand held horns by a long shot. It is also a deeper sound as the small ones are high pitched and shrill. It reminds me of truck horns. I cannot tell how many blasts it has inside, but i tested it five times for about 3 seconds at a time and the can still feels very full. I would not use it as a noisemaker at a party or indoors. Is it damn loud and might do some ear damage indoors.

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! Great when you need it.
