Query: Don't waste your money

The only good thing about this horn is that when it works it is loud. Trouble is you have to place the horn on the handle bars in a manner so that it points forward and the actuator button is on top of the horn. That means you have to take a hand off the handle bar grip to honk. The main reason I honk is that someone is trying to run over me. Releasing the grip of one hand puts me more at risk. The other main problem is that it runs on high pressure air. Any system like that is prone to leaks as did mine after only a few months. It is in the trash now and I am looking for a mechanical or electric horn.
