Neighbors nuisance dogs hate this, thus I love it. LOUD!

Works great, telemarketers hate it LMAO

I pressed it once, it worked. I went to press it again, button permanently stuck in bottom position, no longer works. This is the 2nd time I've tried posting this. What happened to the first one?

This thing is huge. I take it with me on bike rides and have already used it twice on dogs chasing me. My experience was that it works -- if you can keep the horn sealed on the can, which is a bit of a challenge having to rotate it tight every time I use it. At this price, an o-ring or something similar should be provided to keep the horn sealed on the can. Edit: I frost- or air-burned my finger blowing this at a dog who kept coming. The horn will simply not stay in place and when it unseals, the air pressure will literally burn your finger.

I bought this airhorn to scare off black bears who frequently get into our bird feeders and garbage cans. This horn is extremely loud and works !! I tried beating on pots and yelling and these bears just move a little further away and continue mauling the bird feeders. This horn is loud enough to scare them away. Can't beat it for the cost.
