Perfect fit for CNC
Bought the 5mm to 8mm converter. Fits tightly and holds torque well without slipping. Anodizing looks nice too.

High torque holding
Using this on a high-load application. No signs of wear after a week of continuous running. Very satisfied.

Good quality
The coupling itself is solid. Machining is precise. Took a bit longer to arrive than expected but worth the wait.

Works well for steppers
Used it to connect a NEMA 17 to a lead screw. Holds position well. Wish it came with Loctite though.
