Better Than Other Couplers

Have all my lead screws on these now. Still allow some (very minor) movement to compensate for not-so-straight lead screws, but do a much better job at dealing with axial motion than the spring style. Particularly good if you use Z hop.

Better Than Everything Else I've Tried

I've tried the spring-style and direct couplers. Had too much play on the springs and far too much binding on direct couplers. These allow for movement while mimizing the slop. They went a LONG way to reducing the z-wobble you see riding up the face of falt surfaces during printing.

Works great!

These are much better than any of the rigid or flexible ones that I've tried.

Doing what couplers do?

I've swapped my original couplers on all my printers to these and they're nice to remove the horizontal hops you may get on z-moves. Not a huge difference, but nice little upgrades and after a few little things, they add up.
