Size confusion
The product is fine, but I ordered the wrong bore size initially. Make sure to check the product options carefully before purchasing.

Great for camera sliders
Used this to fix my motorized slider track. The coupling fits perfectly on the stepper motor shaft and eliminated the vibration issues I was having.

Solid build
Good aluminum quality and feels durable. Just make sure to measure your shaft diameter accurately before ordering the bore size.
