Review: My prayers have been answered. - 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!!!!!!!!!
Review: Works well - Lost my voice a few weeks ago. It's not getting any better. This is perfect when I'm out and about
