Maintain shaving efficiency: Old bits can become dull after a period of use. The replaced head has a sharp edge that can easily cut off beards. Reduces skin irritation: As the head wears out, it is easy to pull the beard when shaving, which in turn irritates the skin. After replacing the new head, the beard can be cut cleanly and without pulling, thus reducing skin irritation. Guarantee the quality of shaving: After a long period of use, the shape of the head may change slightly, resulting in the inability to conform to the contours of the face during shaving, the replaced head can better adapt to the contours of the face, shave the beard more cleanly and neatly, and improve the quality of the shave. Extend the service life of the shaver: when the cutter head becomes dull, the motor needs to increase the load to rotate, after replacing the cutter head, the shaving process is easy, and the motor and other components will not be damaged due to overwork. Improved shaving comfort: The new head is more pleasant to the touch. The material is smoother when it is new, and it does not feel rough due to wear and dirt build-up like the old bits.
