Has worked well in small meetings to help a participant who has a throat problem Recharges easily and is holding up well. Only using the headset configuration. ### ⭐⭐⭐⭐ Great for price! *by S***Y on December 24, 2024* Honestly, I have used this product multiple times for coaching cardio dance. It’s super effective when my clients need to hear me over the music, easy to use, and easy to recharge! Only issue: wish the headset was a bit for adjustable and could tighten. ### ⭐⭐⭐⭐⭐ The product does what it's supposed to and the company supports its product. *by F***X on December 8, 2021* I purchased this product the third day of teaching a room full of third grader's with a mask on and it has saved my voice! I use the Bluetooth mic every day and connect wirelessly to the speaker on the other side of the room. This is the way I thought I'd use it but now that I've been at it awhile I've discovered that it's perfect for amplifying sound from my computer or the overhead projector I regularly use. Better still, it give voice to my students! I keep the speaker on all day and I turn the microphone on and off. I have NEVER had a battery life issue and it's used five days a week from 8:30-2:30.This should have been enough to compel me to write a glowing review (many of my friends have purchased this on my recommendation) but something just happened that I'm still trying to wrap my head around. Today while a student was reading the microphone inexplicably stopped working. I tried everything to no avail. Fortunately, I had purchased this product with the wired mic which I used until the end of the day. I wrote an email to the company around noon with very low expectations that it would end with a positive result. Unbelievably I have already received a reply email AND IT SOLVED MY PROBLEM!The product does what it's supposed to and the company supports its product.
