Nice Telescoping Boom!!!

I made a mistake of ordering cheap telescoping boom mic stands through Amazon and the plastic locking mechanism broke right away. The K&M unit has a metal locking mechanism which will last a long time, as our original unit never failed.

Great boom for the price!

Excellent boom for the price, nothing out there beats it. I have one on a DR Pro base and a few on heavy MS20e Atlas bases. The clutch knob is a smaller plastic wing, I believe they used to be larger metal ones like the DR Pros use but I just swapped them out and all's well now. Highly recommended! Cheers,Everett
