And a little mod I did to mine: I put some super thin felt tape over the ribbed rubber inside the "hooks" so that it is easier to rotate the boom on the axis of the pole, if you need to tweak it slightly. Obviously you will lose some of the gripping power if it's at a more extreme angle, but not much of an issue if it's fairly horizontal/parallel to the ground.
I made my own Boom Buddy out of aluminum and used moleskin for the same purpose.
