Firechief Air Horn to Raise Alarm - Loud Noise Emergency Horn for Fire Alarm at Work or Office - Non-Flammable 100g Can - Event Horn, Sports Day and More -

A great little Air horn , easy to attach to the gas cannister and its good to be able to replace the cannister rather than a once used having to throw the whole thing away. Actually bought it to use on the road as a cyclist who has experienced people dressed in black randomly walking out on me early mornings , or walking in the road when there is two perfectly good pavements to use , so desperate times need desperate solutions and this air horn definitely works. Hint : It fits into a water bottle holder. Happy I was able to find an air horn that didnt need pumped or blown by mouth.

Very loud

Fairly hard to use

Put my ear defenders on, lol :) Such fun!!

Great protection
