Regarding this high-quality electric toothbrush
Features:

Compared with manual toothbrushes, the plaque removal rate is as high as 7 times.

High cleaning frequency: up to 42,000 times per minute at most.

Help develop a scientific tooth-brushing habit: A 30-second to 2-minute smart timer that triggers a handle timer every 30 seconds, allowing you to know when to change the oral area. The last 2-minute tooth-brushing reminder helps you form the tooth-brushing habit recommended by the dentist (the best recommended tooth-brushing time).
High-quality high-density bristles: Antibacterial and durable, penetrate deep into the Spaces between wisdom teeth and gums, and quickly clean dental plaque.
The entire body has a waterproof layer, and the base is a waterproof pad, which can be directly cleaned with water.
It's about 30 days (twice a day, 2 minutes each time), so there's no need to worry about the charger when traveling.

Usage suggestion: To achieve the ideal oral hygiene effect, it is recommended that you replace the toothbrush head every three months. Long-term use of the same brush head not only reduces the cleaning power but also easily breeds a large number of bacteria, affecting oral health. Replace the brush head regularly as recommended and, in combination with the efficient cleaning function of the electric toothbrush, keep your mouth fresh and healthy at all times.
