The Infly T04B is a sonic electric toothbrush designed to help children aged 3 to 15 maintain a healthy smile. It utilizes high-frequency sonic vibrations reaching 33,000 per minute to remove plaque more effectively than manual brushing, offering three distinct modes for cleaning, polishing, and whitening depending on the child's needs. Constructed from lightweight plastic, the blue handle weighs only 84 g and measures 198.2 mm in length, making it easy for smaller hands to grip and maneuver. The brush head features medium-hardness DuPont bristles, which are gentle on developing gums while remaining effective at cleaning. For added convenience, the device is IPX7 water-resistant, allowing it to be used and rinsed safely in the bathroom. Charging is handled via a USB Type-C cable and a playful whale-shaped base. A full charge takes about 3 hours and can last up to 60 days, meaning you won't have to worry about frequent recharging during the school term.
