Perception research defined the proportions of the bristle head design, balancing the perception of performance with real brushing time. A rubber Pinch Grip Zone for fingertips optimizes dexterous control and tactile feedback. C. A non-slip rubberized Power Grip Zone provides overall grip security with slippery hands.
