It holds my mic firmly in place despite how I twist and turn. Now my mic isn't the heaviest one (AT2020 XLR), but no issues whatsoever. I haven't tried any more expensive ones, so I don't have much to compare with. But considering it works just the way I want it to, the fact that it comes with an XLR-cable that runs inside the arm itself and for the price tag of it... nothing to complain about!
