Compatible with Braun 40B, CT2S, CT4S, CT2CC, CT4CC, CT5CC, and CT6CC2 models. Made from high-quality materials for durable, efficient, and easy-to-use performance. For optimal shaving results, it is recommended to replace the shaving head every 18 months. After 18 months of use, the electric shaver may have cut over 6 million hairs, which can gradually reduce cutting efficiency. The replacement head features advanced processing technology to enhance the shaver's texture and appearance. Replacing the head helps restore the original performance of the shaver, delivering a closer and more comfortable shave. Regular replacement ensures long-term peak performance.
