Improves shaving efficiency: Changing the shaving head is sharper, making it faster and easier to shave and reducing the time it takes to shave. Improved shave: Changing the shaving head conforms more closely to the contours of the face, capturing and shaving shorter, finer hairs, ensuring smooth, residue-free skin after shaving. Extend shaver life: Replacing the shaver head regularly helps protect the shaver's internal mechanics from excessive wear and tear, extending the life of the entire shaver. Optimized battery life (for electric shavers): For electric shavers, a clean and sharp head reduces the workload on the motor, and replacing the shaving head indirectly increases battery life
