Fit good
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
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.
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.

Fit ender 3 v2
It was a drop in fit for my ender 3, but it did not solve the issue of the z axis binding. I am still working on fine tuning the printer.

Easy install
Quick and easy installation, used on upgrading Ender 3.

Too many issues, cheap mat
The cheap set screws get stripped out easily and become stuck. Making the whole thing impossible to remove without ruining the lead screw. Also they are way too rigid

Good
Work great

An additional point for failure- not a solution
I got these after investing in a second screw. The verdict? A pain to set up. I don't know if my collar's insides were just made too narrow somehow, but my screws can barely get down in them while loosened up, and they have a habit of randomly popping in half, completely ruining a print and- god forbid- maybe even damaging other components of the printer, if not present.
