Hand Pump Air Horn – Reusable Blow Horn for Raising the Alarm in Emergencies – Loud Noise Foghorn for Fire Warnings, Events & Raising Alarm in the Workplace & in Offices

Flimsy build, it's intended as a single-use toy. Items of this quality You would probably find it in a pound shop.Still, I use it for a scientific experiment. Works very well; it's extremely loud, enough that your ears hurt right away. Use hearing protection!How long will it work is another matter.

Simple to use and very effective in making a noise

Absolute rubbish, falls apart , can't get it to sound. Don't waste your money

When this first arrived it was in self-assembly pieces in a plastic packet and didn't look or feel all that impressive. It took all of 30 seconds to assemble and it makes a really loud noise! The handle is pushed up from the bottom to create the air flow. There is the facility to 'close' the handle up for storage by screwing it into the base, and sometimes in use I accidentally twist it and the handle gets stuck. Not much use in the middle of celebrating the NHS and I'm busy trying to coax the handle out again while everyone else is busy banging pans. Other than that, great value and great fun.

A little stiff to use and sometimes the plunger comes out of the body - but sound is good and noisy.

Great quality.

Very fragile, fell apart first time I used it, had to reassemble it to try again, gave it away in the end.

This wasn't very loud. Quite flimsy productI bought this to scare pigeons off my roof as they poop everywhere but it didn't workThis is best used for parties etc but not for sure alarms etc as its not loud
