Instructions for use:

This device requires both eye and hand skills and primarily tests reaction speed.

Reaction speed depends mainly on the senses (vision and hearing) and the coordination between the central nervous system and neuromuscular system. 

Operation:

Participants press the start button on the front of the device, then insert 10 round rods into 10 round holes.

 After pressing the start button again and counting down 3 seconds, the 10 round rods begin to fall randomly.

Participants must quickly catch them, and the number they catch at the end is counted.
