I have a snowball mic on the end of me mounted on a vertical surface about 36 inches from my desk. It sticks out about 2/3 of the way before I folded it down to bring it closer to my head and position the mic properly. This helped remove my keyboard noise recorded on my computer. The real sound of the keys is still picked up by the excellent microphone, but no longer the rattling. This mic is still hanging in the same place after 2 months. Sometimes, due to the positioning, I do bang my head on the mic if I lean forward before getting up, but that's why I chose the gooseneck to intervene if I accidentally bang it. Most of the time I even forget it's there, but I can rarely adjust it a bit after an impact and it stays in place. I think a heavy mic might not mount right out of the housing it's screwed into, but with a little flex it works great. It curves up slightly at first (fewer headbangs), then curves down from about 11 inches and the mic mount is 14 inches from the body at the end point (for this 19-inch mount). See photo.
