The beautifully crafted toothbrush uses ultrasonic technology to send vibrations of up to 31,000 per minute to our teeth, in order to provide a really powerful cleaning procedure. It also has DuPont StaClean high-quality bristles and a waterproof body with IPX7 ratings, so you can use it safely under the sink.
Just as anyone would expect, the Mi Ultrasonic Toothbrush has smart personalized custom brushing modes that can be customized through a smartphone app easily and packs a 700 mAh battery that provides a battery life of up to 18 days when used twice a day. If you need to charge it, then you can use a small charging dock that can be powered even using a power bank, so it is easy to carry when you are travelling.
According to Xiaomi, the Xiaomi Mi Ultrasonic Toothbrush will be available in China starting July 18, at a price of 199 yuan ($29).
