Solid Build
Good coupling but delivery was slightly slower than expected. The quality of the aluminum is top notch and fits my motor shaft perfectly.

Excellent Precision
Used this for a servo upgrade on my lathe. The runout is minimal and installation was straightforward. Highly recommended for precision applications.

Works Well
Fits my NEMA 23 motor perfectly. Screws provided were good quality. Would have given 5 stars if shipping packaging was more robust.
