Just installed it, okay guys don't expect too much with this money, it has intensity but not 100 watts as it says, not even 5 watts, the car horn is louder to understand the intensity. I don't know how long it will last, time will tell. But for effects, it's good to mess with the kids in the neighborhood or your friends, don't expect to use it to scare off ten cars in front of you, they will just move aside, besides it's illegal to do something like that, let's tell the truth, you can get in trouble just for having it installed, you don't even need to cause a scene to attract attention, a search by the police is enough. So BE CAREFUL, those of you who install these horns, we don't use them wherever we want!!

Flawless and very powerful. For an emergency hour, it is just what you need for warning when the horn is weak.
