If you have minimum hand and wrist strength, we highly recommend you purchase the Tri-Pin Spinner Knob over the other spinner knobs. The Tri-Pin allows the user to place their hand and wrist between the 3 pins, giving the driver maximum control of the steering wheel with both their hand and their wrist. This design is great for people with less dexterity and hand strength. 

MAIN FEATURES :

• The Tri-pin Spinner Knob attaches to the Steering Wheel Attachment Base 

• Quick-release button allows you to easily mount and dismount the steering wheel attachment
