### ⭐⭐⭐ 







  
  
    Thinking They Might Work.
  

*by J***N on Reviewed in the United States on October 15, 2020*

Seemed lower quality than the ones I am replacing. Using in a telescope focuser so won’t be moving fast. First one wouldn’t turn well so tossed it. 2nd one rotated fine. Seems to work. Tolerances seem good enough. Glad there are 10 hoping half work. Not much quality control in these Chinese products.

### ⭐⭐⭐ 







  
  
    Tolerences
  

*by B***E on Reviewed in the United States on December 19, 2019*

The ID tolerances on these are pretty loose; the closest one to listed spec was 3.08mm, the worst 3.12mm, with most being 3.10mmThe OD's are pretty close.

### ⭐ 







  
  
    Poorly made
  

*by Z***I on Reviewed in the United States on March 13, 2020*

Very loose tolerance, will rattle badly under a few thousand RPM
