Usual good reliability and 'easily-adjustable' K&M quality, but be careful of weight distribution stability if used to laterally extend a mic shock mount on a desktop stand; it will need a counterweight to use the fullest length of the arm, or a slightly longer K&M Boom arm if you have sufficient room behind the arm.
NB This has European 3/8" thread, so attaching it to American style 1/2"supports and shock mounts will require thread converter rings. (I had to do this to use it with some Antelope Audio gear). It should be excellent for short distance/height mounting on stable floor stand mic stands (EG near drums, speakers, basses etc,)
