Jean for one the problems you wrote about are shared by many. My Mic. Stand has a tri-part base so when extending the boom with the Mic. On it tends to lean --- so I have a felt around the stand where it rests against the keyboard – Two parts of the tri-stand are on the outside and the other part with the Mic. is resting on the keyboard.

The boom that drops:
I tried putting in new pressure pads, it’s a bit of a job. Since the stand is always at the same height ( I make sure that when I extend the stand it it’s always the same height) I drilled a small hole and put a small hinge pin into the boom where you tighten it. Please don’t lose the pin.
