## Customer Reviews

### ⭐⭐⭐⭐⭐ Fit good
*by M***D on April 7, 2022*

I got these for my Ender 3 Pro which I upgraded to have a dual Z axis. They work good and I have not had any problems with them.

### ⭐⭐⭐⭐⭐ Fantastic coupler
*by M***R on February 5, 2021*

This replaced a 3d printed coupler that could never be tightened enough. With this there is no more slip.

### ⭐ Poor quality and out of spec.
*by A***R on February 22, 2021*

These couplers are of a very poor quality. The first coupler I used cracked when tightening the screw on the 8mm side. The second coupler took an to much torques to be able to adequately grab either the 5mm or 8mm side. Luckily these were cheap and I'm not wasting time sending these back and just ended up in the trash. I would highly recommend looking elsewhere for couplers.
