Good value
Works well for the price. Instructions could be clearer on torque specs for the set screws, but overall satisfied.

Solid build quality
The stainless steel version holds up well in our humid workshop environment. No signs of corrosion after three months.

Reliable connection
ZJM expansion sleeve type is very easy to mount. Saves time during assembly compared to keyed couplings.

High speed performance
Running at 8000 RPM without vibration issues. The balance seems excellent out of the box.
