One of many testimonials:

"While riding to meet up with other Harley buddies, I noticed a young girl moving from side to side in her lane. When I got closer I noticed she was texting someone and did not realize she was starting to move into my lane (we were traveling at 70 MPH). I first applied my stock horn with NO luck as she was also listening to very loud wasn't until she heard my BANSHEE that she pull her car back in her lane by missing my Bike by inches......Thank you Screaming Banshee for saving my life!"
