I bought it for my classroom and it worked great! However, after 4 months of daily use in the classroom, it stopped working out of nowhere. The speaker turns on and after a minute it shuts off. Double checked to make sure it was charged. Looked up videos to make sure microphone and speaker was paired correctly, and still didn't work. I've had cheaper amplifiers that lasted years. Disappointed.

This SHIDU voice amplifier is perfect for teaching and presentations. The wireless lavalier mic has great sound quality with no noise, and the 40m range is impressive. Lightweight and comfortable to use without a headset. Battery lasts all day, and Bluetooth is a great bonus. Highly recommended!

I am a PE teacher and use this in my classes. Plenty loud when using the mic, just wish the battery lasted longer than one day. I tried the bluetooth function to play music from my phone. Not very loud.

This voice amplifier is very powerful and portable. I like it because it has a clear loud voice. Very useful in Sunday School classrooms and also in scout camps. The battery is enough for use multiple days. The Bluetooth helps with playing music and songs. Check out my attached video. I highly recommend it!
