Great! It works well, exactly as described

I've been using it for 2 years, and it's good news that it's still working. The negative part is that the sound quality when speaking into the microphone can be improved, some people find it hard to understand me when I speak into the microphone.

A compact amp with strong reproduction qualities. As described by my sister. I have throat cancer, the amp didn't suit my situation, which is a bummer because it's a great little product.

I can't praise this amplifier enough.In 2015 I had cancer of the larynx and went through 6.5 weeks radiotherapy. I count myself extremely fortunate that I didn't have the larynx removed leaving me unable to talk at all but my larynx has gone through a lot, leaving my voice very variable. Sometimes gruff and growling, sometimes barely audible and a great deal of effort and strain is required to vocalise at all.At long last I have seen a speech therapist, who has given me voice exercises and techniques, but also suggested getting an amplifier. I am a carer and see a lot of people who are hard of hearing. Repeating myself has taken its toll on my voice.I bought this amplifier, it is really easy to use. I can adjust the volume to suit the clients hearing ability and my own voice is "cleaned up". The amplifier seems to smooth out my voice getting rid of the growling, gravely sound. My voice is much clearer and I no long have to strain to be heard or repeat myself over and over again. How I wish I had known about this all those years ago, but hey I'm not complaining, I've found the answer now.Highly recommended!!!!!!!!!

I bought this to help me teach language in classroom , this Voice Amplifier is quite small , and very easy to use , ideal for a large class / meeting room, save me to shout and improve the teaching quality. Totally worth the money.

Perfect, lovely bright red colour, good design, not too boxy, works well for my purposes (busking). Couldn't ask for a better birthday present.

really easy to use but 9 months later it has already stopped working.

Lost my voice a few weeks ago. It's not getting any better. This is perfect when I'm out and about
