I use one of these for a replacement for a gooseneck podium mic and the other five I purchased to replace Standard table microphone which I've been using for panel discussions in our Digital Auditorium. Great clarity and the users do not touch the during events which eliminates unwanted noise.
This product is used almost exclusively to record meeting. We are very satisfied with it's performace.
For it's purpose this mic is great. I use it to record audiance participation by placing several around large rooms while video taping events. It is not likly to be mistaken as a PA mic so pepole leave them alone.
