Review on SIENOC Linear Motion Shafts Hardened by Josh Whitehead

Both rods I received measured 7.97mm at all points. It's pretty accurate and very consistent. However, the endings are terrible. They look like they were cut with bolt cutters and then the edges were smoothed. I didn't manage to get a picture that shows it clearly, but when I hold it in my hands and rotate it, you really see it. I measured carefully and noticed that the bumps on the ends are only in the axial direction. The diameter also remains constant at the ends, which is why I only deduct one star.
