The Combined Power of Electrons and Sonic Waves. Discover the Future of Brushing. SOLADEY RHYTHM2 is a brand new type of brush that harnesses the power of sonic waves and electrons to keep your teeth healthy and sparkly clean. Experience a refreshing clean like no other. Removes plaque using sonic waves and electrons. The effective powers of electrons and high-speed sonic vibrations combine to remove stubborn plaque and cavity-causing bacteria. Honeycomb-Point Bristles The honeycomb-shaped (hexagon) bristles deliver a thorough and satisfying polish every time, while the pointed brush tip cleans deep between teeth and around the molars. Specs Body material : Acrylic Resin Bristle material : Nylon Bristle hardness : Regular Battery type : AAA Alkaline Dry-Cell Battery Approximate : Acrylic Resin High Mode : Approx. 22,000 vibrations/min Standard Mode : Approx. 18,000 vibrations/min SOLADEY RHYTHM2 Features Sonic vibrations at around 360 strokes per second Watch as your teeth become smooth and squeaky clean thanks to technology that is easier, faster and more reliable than conventional brushing. *Approximtely300 strokes/sec in Standard Mode Solar Panels + TiO2Semiconductor The brush effectively removes plaque by emitting large numbers of electrons. The electrons coat the teeth entirely, ensuring they remain sparkly clean even 12 hours after brushing. MADE IN JAPAN Semiconductor-equipped toothbrushes are recognized as having high plaque removal effectiveness by the International Institute for Preventive Dentistry, Japan Dental Association, etc. HOTARU Lamp The blinking LED light indicates the generation of electrons. Witness the chemical actions firsthand and enjoy a fun and easy way to check the progress of your brushing each day. Select the strength that best matches the sensitivity of your teeth and gums. Use the handy button to switch between Standard (18,000 vibrations/min) and High (22,000 vibrations/min) modes. Select the mode that best matches your brushing strength and the sensitivity of your teeth and gums. 2025 U.S. FDA REGISTRATION SOLADEY is FDA registered in the USA by Registrar Corp (2025). Please buy it with confidence. How Soladey Rhythem 2 Works When light strikes the solar panel, electrons e- are created. These electrons e- proceed from the minus pole toward the semiconductor along the lead wire.When light strikes the moistened semiconductor, electrons e- are created (photocatalytic action) . Together with the electrons e- created in [1] , these electrons e- move into the inside of the mouth via moisture such as saliva.These double electrons e- remove the hydrogen ion H+ in plaque, making it unstable.As a result, plaque is easier to remove, and brushing has a greater effect on achieving healthy teeth.
