Review: Buen producto
Review: too tight - Fit was too tight as if bearings were oversized, had to chuck this and buy a different one that worked way smoother...but for twenty bucks what do you expect?

### ⭐ too tight
*by V***A on April 13, 2025*

Fit was too tight as if bearings were oversized, had to chuck this and buy a different one that worked way smoother...but for twenty bucks what do you expect?

### ⭐⭐ 2 of 3 do not fit the thread correctly.
*by M***W on July 8, 2024*

I have ordered 3 of these, out of the 3 only 1 fit the screw rod i needed to. the other 2 Ball screw net felt like the thread pitch was not right in them and would just bind or pop off the white caps.
