Review: speaker for a classroom - This item served its purpose. We had a retirement party and there were about 33 people there. Some people talk softly and cannot be heard, especially when there's a group or crowd. The microphone worked great!.
Review: Do not buy - I ordered this too far advance of the event I got it for so can't return it. I ended up having to just yell when giving my grandmother's 100th birthday speech because it kept going in and out and didn't work.
