On-Stage MSA-9508 Posi-Lok Side Mount Boom Arm

Most Liked Negative Review

Really well built but one major design flaw

I really like the quality build, finish and stability. I downgraded because of the one sided vee clamp. The clamp consists of a vee shaped piece that goes against the back side of mike stand post and a simple screw that presses against the post from the side that bears the weight of the mount. This is a pressure point that can easily cause damage to the mike stand post. All the weight of the microphone and mount (including goose neck if you use one) come to bear on this tiny point of contact against the vertical mike post. If you screw the clamp too tight it will cause a dimple impression into the post and restrict or prevent adjusting the mike stand height. A severe bump into the mount could also cause this damage. On the plus side, I find that this screw does not need to be tightened much at all to provide a very stable side mount. I feel a better design would include a matching vee piece attached to the screw. This was a test purchase for our acoustic society. We need 4 or 5 more side mounts, but will be looking for something else with less potential to damage.
