FrameworksGFW-MIC-2621 Microphone Stand Bass Drum and Amplifier, Compact Size

What is the base made out of, and how does it do with vibration? (for use on a computer desk)

What are the dimensions of the base?

My fifine mic has a 3/8" female adapter. this stand's mic connector has an externally threaded 5/8" thread and internal 3/8" thread. how to fit?

Will this fit the presonus M7 mic?
