Question: Does this horn work if it gets turned upside down or is stored on its side?
Document: This horn does not work! Only blows air. No sound. And now I find out I can't return it! Do not buy this horn. Even if it did work it would last about 20 seconds! Amazon needs to have the fact that you can't return this horn in large bold type.
I can't make it work, I don't want to keep trying it, I don't see that way to cause the horn to sound. I didn't send it back because getting into the packaging made it impossible to keep the packaging intact and so no way to reassemble and send back. I wouldn't buy this again.
I bought this air horn for my survival kit. It is very loud, and efficient. But don't let looks deceive you. This horn is very small. It also is very dangerous. Do not bring it around kids. It will cause hearing damage. When you sound the horn, make sure you hold it away from your face. If you hold it too close, it will hurt your ears. Also, do not hold it sideways or upside-down.
The horn is at best adequate, but the real problem is that half the canisters we've ordered have been empty (over two separate orders). If you intend to purchase this product, buy twice as many canisters as you think you'll need. Perhaps half will work. (We tried to work with Falcon Safety customer service but got no help. You're on your own.)
I had purchased the identical horn a couple of months ago from Amazon, and it worked great, so this is not operator error. This one would only give off a hissing sound with the gas escaping but no blast like the first one. After reading other reviews it sounds like you are lucky if one out of two work. I wouldn't recommend the gamble.
I have a high strung, leash reactive pit mix. I've tried every other non e-collar training trick out there...they'd work for a week and then she'd build up a tolerance. My trainer lent me a cheaper small air horn as a corrective tool when she spazzes (some doggie daycare places use it to break up barkfests)...it worked well, but fell apart quickly. This product is really well made.
I got this horn for home protection, as I read where a guy interviewed several career burglars in prison and the thing that would drive them out of a house faster than an alarm or barking dog was a loud air horn. Think of it as a poor man's portable active denial system. I was skeptical at first, but when I sounded this horn, I was convinced it would work. It is supper loud and completely annoying.
Bought a few of these for my daughters outdoors graduation.Fantastic!The size is extremely small (fits within your palm) but the sound is full-size.You can keep them on you and not have it be obvious.Will keep them around for other uses.It even works upside down.
This thing does not work at all, just blows air with no sound. Problem is it is not returnable. Not happy!
They are good for what I need them for. We use them to separate the dogs when the fight and work.
Answer: yes
