Garic,
No hands-on experience with this Czech-made Regal clone, but from what I see and based on Regal experiences I am not impressed.
Provided the build quality is Regal-like or better, the holding of hooks across a range of sizes should be well covered.
The rotary part will be sub-standard, imposed and limited by the jaws design. Way too much bulk away from the axis to spin easily, and when hand-cranked or inverted the jaws physical bulk will restrict access to the hook.
It would not be my choice. Your mileage may vary.
Cheers,
Hans W
