It's a spinner, what's the problem going lock to lock, just like using a ball spinner.
The location depends on the strength of each arm and the strength of individual muscles. Bottom center works for some people, while others place it higher or lower on the right and left side. A person who had not used one would have to try various locations and perhaps be tested by a physical therapist or doctor to be sure they had the strength to drive from the starting position and were not doing damage holding their arm there.
The counter balance matches the aid so that the user does not have to cope with the weight of the aid.
