Good value, minor finish issue

Functionally works great for extending my motor shaft. There was a tiny scratch on the side, but it doesn't affect performance. Would buy again.

Does the job well

Exactly what I needed to connect two different shaft sizes. Installation was straightforward. Just make sure to tighten the screws evenly.

Perfect fit for my CNC project

The machining quality is excellent. I used the 10mm to 12mm adapter and it fits snugly without any wobble. The set screws hold tight even under load.
