They work and the knob so far stay attached, not sure what else you look for in a review of product like this?

    Essential Spare Part for Folding Microphone Stands
  

*by E***D on Reviewed in the United States on March 14, 2020*

I bought these knobs as replacements for the original knobs on K&M microphone stands, which tend to go truant at awkward times. The knobs are threaded M6x1.0, which the correct size. A nice feature is the lobed design of the plastic knob, much easier to tighten than the round OEM knobs. They're a little long, but fit in all positions of the stand, including the base and boom arm.
