This and one other thing is the first bad thing I'm hearing about it. The other bad thing which well seems bad to me at least, is on the G-Clamp desk mount, the arm wobbles about in there. Now granted I don't have a mic attached yet, but it's like it's missing a piece to make the fit snug and secure in there.
The through desk mount, is perfect, however.
I'll be using the G-Clamp mount for a number of weeks until my new home office/gaming nerd cave is all setup, so I'll soon find out if it's an issue or not.
I ended up going with the Blue Compass instead. Much nicer!
Just need to really play with that tension screw in the bottom to stop it flying up.
