### ⭐⭐⭐⭐⭐ Great for teachers on duty!

### ⭐⭐⭐⭐⭐ Megaphone

Awesome product. Very clear and loud.

### ⭐⭐⭐⭐⭐ Fantastic megaphone with the alarm sound as well great value for the money!
*by A***R on October 14, 2025*

I absolutely love this megaphone unfortunately it's not with me at the moment to do a video. I keep it at a ranch where I have a hangar and an airplane and I have a lot of Critters that get in my hangar, while I'm out flying around when it's time to go home and close up I usually sound the Horn which scares a variety of small Critters out of the space. It's the only way to make sure they're not locked in when I leave. Sometimes my little dog decides to go out on adventure through the woods nearby and I use it to call her back which is also very effective. The thing works great and very happy about reviewing it highly recommended and you won't find anything better for the price
