I frequently get cut off on my motorcycle, and the last time this happened, a car merged right into my lane on the freeway while I was occupying it. I was on my stock horn, and I realized that I couldn't even hear it very well, and the driver cutting me off certainly was oblivious to my presence. This one i can hear and i am more than certain others will hear it too. Very impressed, especially for the price, can recommend it to everyone.
