Buyer rule
Start with room, mount, and signal path
Start with microphone weight, shock mount weight, desk edge, monitor position, camera frame, typing distance, cable route, and whether the arm must swing away.

Buyer rule
Start with microphone weight, shock mount weight, desk edge, monitor position, camera frame, typing distance, cable route, and whether the arm must swing away.
Risk
The common mistake is buying a light arm for a heavy microphone or placing the clamp where it blocks monitors, keyboards, or stream controls.
