Not great. The coupling can be pulled apart by hand. If your two shafts exert tensile force (i.e., are pulling apart) along their axis then this coupling can fail. I wanted to use this to turn a lead screw which supports a panel that contracts and extends. This exerts an axial force on the coupling. I reinforced the coupling too with a 8-32 lead screw to ensure the motor shaft and the lead screw are fixed securely to the coupling.

Yeah, I definitely crashed a head while fighting with a difficult print. These easy-break away features saved me from doing much more damage.

I built a Z-Axis lift for my Precision Matthews tabletop mill and was getting serious vibrations from the gearbox to the Z-axis linkage. This looked a little flimsy to me at first, but has been working like a champ for over a year now in frequent use.

If your Z-rod is slipping on your Ender 3 Pro, these are a great replacement

The coupler is nice, high quality and works great.The only problem is - it tightens up only against a solid 8mm rod. If you attach it to a threaded M8 rod, there is no way to tighten it up to hold a torque.There is plenty of room to drill perpendicular holes and tap M3 thread. Perhaps, even M4 would fit. I did M3 and it works well. But it would be nice to have a better locking mechanism in the first place.

Good quality bushings but incredibly difficult to tighten up properly.I've had to tighten the screws up 3 times since fitting due to it slipping.

easy install, just enough flex to keep things aligned. a must to reduce or eliminate binding and misalignment issues
