Review on W WINBRIDGE Voice Amplifier: Portable Microphone and Speaker for Effective Personal Amplification – Ideal for Teachers, Elderly, Coaches, Training, Presentations, and Tour Guides by Jason Hayes

I bought this for my personal practice concert as the music gets very loud in my center and I work with elderly clients who are hard of hearing. I did a test run at home first before doing anything and I would advise being careful with the mic setting while the unit is on (it creates annoying high pitched feedback noise). Maybe it's the wiring itself, but don't even turn it up to medium volume when you're pitching the mic. 4/5, does the job for the price but I could do without the loud feedback noise lol.
