Superior Performance
Voluntary closing terminal devices offer superior performance to the limb deficient.

Quick Adaptability
Training is no more difficult with voluntary closing; gripping force range is expanded and directly proportional to output.

Intuitive Operation
Voluntary closed terminal devices offers intuitive operation, accurately controllable pinch force, and inherently good quality feedback of force and motion.

Assist in  Muscle Growth
Muscles of the torso and limb are used more actively.  Healthy, and strong muscles can only  enhance externally powered control and utilization.

Superior Gripping 
Voluntary closing systems can achieve gripping prehension which equals or exceeds user’s anatomical capabilities.
