Rated 4 out of 5

Excellent Counterweight

This counterweight is of high quality and easy to use and adjust. The only suggestion would be to make it heavier for applications where the boom is too short to balance out the mike. The difficulty you might find with most of the K & M stands and booms is the plastic handle at the end prevents adding the counterweight. This is removable with difficulty. I used a hammer and a V-shaped machinist platform to knock it off. It is not that hard to put back on. Probably heating in nearly boiling water would also be a way to make it easier to remove

Mic Boom Counterweight

I have experimented for a long time trying to get a mike boom to stay up with the weight of the mike on it. No clamps so far have been strong enough to keep the boom horizontal no matter how tight you torque it down. Eventually they all droop, so this was the answer. They used to come standard. They're a bit pricey, but worth the cost for peace of mind when recording.
