SHOCK ABSORPTION AND NOISE REDUCTION TECHNOLOGY: kissday has aslo found that most electric toothbrushes on the market have poor noise control, causing users to feel annoyed by the harsh noise. Starting from the body structure, we pioneered the airbag noise reduction technology. By optimizing the body structure and integrating airbag black technology, the noise of the electric toothbrush is reduced to 40.2dB, helping users to brush their teeth without feeling annoyed. SPEEDTEK ONE-CLICK CLEANING: kissday has found that most electric toothbrushes on the market have up to 4-5 modes, but in actual use, there is no significant difference between these modes. Therefore, we refuse complex parameters, say goodbye to cumbersome and useless functions, and only keep the two most useful modes. With just one click, it can meet daily brushing needs. ULTIMATE GUM CARE: kissday dares to break the traditional toothbrush head constraints on the market, cutting three different types of bristles into arcs and widening the area of bristles. The bristles can cover teeth 360° accurately and achieve strong teeth cleaning, while the soft and gentle bristles with a 2mm drop can ensure that the gums are not stimulated and the enamel is not damaged but achieving efficient teeth cleaning. Friendly to beginners, the elderly, and those with sensitive gums.
