...it toots. I had one before, but the first one broke. So I bought it again. So far, my calls have always been answered. :-) I don't know what else to say. It's better than a vuvuzela from a gas station and easier to install than an air horn with a compressor. It's always ready to use as long as the user is still breathing—even at the ends of the earth at night during a power outage. I really appreciate products like this.
