Microphone feels good in you hand, sturdy.
Cons:No part(s) availbilty to the consumer.
I run a DJ/KJ business and have 2 of these units along with an extra headset. I have never had any problem within the last two years. They are very clear and have a long range and battery life. They have been dropped and still work fine. The field replaceable modules are a plus if one module fails.
