Voice Booster VoiceBooster Voice Amplifier 20watts Black MR2300 (Aker) by TK Products, Portable, for Teachers, Coaches, Tour Guides, Presentations, Costumes, Etc.

Works well , however I had hoped the unit was a bit more compacted .

I saw one of these in use by a tour guide at the Cheyenne WY Super Computer site. Since I do tours of a major international auto show here in Washington DC, I hoped it would work to make my voice heard in the noisy convention center hall. It worked great. I learned to turn it down or off in tight spaces like elevators. But quite happy with the performance of it. Other tour guides and sales folks asked about it Great value for the money.

I am a tour guide at a distillery in Kentucky. I had surgery on my vocal cord and the doc suggested I use an amplifier for work. After extensive research I decided to order the Voice Booster 20 watt. I was quite pleased with the sound quality and projection. Even near full volume in a very noisy environment, they're was very little distortion. The unit it's fairly light, and while I wish there was a belt clip, the strap was easy to adjust and stayed put around my waist. My only complaint is that after about 2 weeks, the mic developed a short and created a lot of static. I contacted the company and they sent me a new headset in just a couple of days. Unfortunately, the new headset has the same problem, so it might be the amplifier unit itself. I can make it work but it's "touchy". Overall I like the unit, but I'm concerned about its long term durability.

Hi and Happy Holidays, The VoiceBooster is a superb and excellent product. The CLARITY OF THE AUDIO IS CRYSTAL CLEAR. I am a retiree and also work as a school bus driver. Being that there is no built-in public address system in the bus, the VoiceBooster is a high-quality substitute product. As anybody will tell you, you have to constantly keep raising your voice to make the kids quiet down. Back in late September 2015, I started losing my voice. That's when I had the idea of wanting and buying a portable P.A. system. I thank God so much that such a product like the VoiceBooster exists. This product has REALLY helped save my vocal chords. On a scale of 1 to 10, I give this product a big 10. Again, thank you so very much for solving my problem. This product is a life saver.

I work as a tour guide in a museum which is often full of school classes and very noisy. This amplifier does the trick. (I have tried other personal amplifiers and been plagued by feedback.) I can turn the volume of this up to maximum and still get no feedback. I have about four hours on the initial batter charge and the indicator light is still bright, so I anticipate good battery life. I highly recommend this product. It works best with the headset microphone which came with it. I have tried it with several tie-clip mics and all produced a lot of feedback. It would be great if the manufacturer could come up with a tie-clip mic which works with this unit. Tie clips are more comfortable and less obtrusive than headsets.
