Well built/LOUD!

This is a fantastic build. As I was trying to do it myself I was impressed with how it came out. The horn is super loud as well; I can't even imagine what the bigger ones sound like.

My son plays high school football 🏈. I use my Boss Horn to cheer on our team. At first people looked at me as if to say, are you crazy? Now several others have them. Every Friday night the team enjoys hearing the Boss Horn support from the crowd! Go Rams 🐏

I am in the stands at a 10u state championship!!!!!
There are a lot of horns, some look like the one I have. The must have bought cheaper. Mine blows them away. BossHorn is the best.
