Handheld Air Horn, Aluminum Portable Handheld Air Pump Horn, Loud Noise Maker Safety Horn for Boats Sporting Events Camping Reusable Eco-Friendly (Handheld air horn 4pcs)

I initially ordered two 4-packs.so that I will get 8 units. One unit in each box was defective. I shipped the two defective and two functional units for an exchange with a new 4-pack as there was no option to return just the defective units. I just got a replacement 4-pack, which contained two defective units that can be combined into one to allow 3 units to be functional. Now it looks like I need to return the whole box of 4 for refund.

Purchased Air-Horn for backup. Scare off Coyotes & personal safety. I tested all four and they are remarkably loud. I opted for the “Handlebar” style, knowing it will work every time. The push button pumps seem to work intermittently & not very loud. Will attach a cord between the horn & canister, so I can carry the unit on walks and ready to go if need be. Hopefully, I will never have to use it. Would absolutely purchase again.

I run a kennel and in very rare cases we might have a little tussle with some dogs so these are at all corners of the property and employees use the airhorn to break dogs concentration and in rare cases a 2nd airborne sound for backup.
