Review on 📢 TK Products VoiceBooster MR1505: Powerful 12w Voice Amplifier - Ideal for Teachers, Coaches, and Presentations! by Doug Powell

This item is fantastic! Used it for a large convention. This allowed me to keep my voice after several days of continuous communication with visitors to our stand. In the past few years, I would sometimes lose my voice or have a severe sore throat by the end of the week. With this device (as well as the low-profile, lightweight, mono-ear VoiceBooster omnidirectional microphone) I was able to speak at a relatively normal volume, but was heard over the noise. my suit jacket. I've never had battery drain issues (more than 8 hours a day). I'm not sure how long it will last, but I haven't had any problems at all. I charged it every night. All in all, I am very satisfied with the purchase and can't imagine running a large trade fair stand without it in the future.
