I love this amplifier. I’m a middle school teacher and this is perfect for me. It’s super handy and easy to carry. Awesome sound quality; very audible. Really helped amplify my voice in the classroom. This should be in every teachers’ wishlist.

### ⭐⭐⭐⭐⭐ Perfect for teaching outside!!!
*by A***H on September 26, 2022*

Teaching PE outside its important to be heard over lawnmowers sometimes, and this is an absolute life saver. I can use a speaking volume and students hear me over quite a long distance! Great item!

### ⭐⭐⭐⭐ Useful
*by S***E on August 29, 2022*

This amplifier is really useful for teachers like me. I really like this because it is lightweight and for long time use without charging again and again. Small flaws for me is that you need to put the mic really near to your mouth so it will be that loud. But over all I will recommend this to my colleagues.
