The high-frequency toothbrush Niceboy ION SmartSonic utilises as many as 40,000 oscillations per minute to effectively care for your pearly-white smile. With the mobile app, you receive a detailed analysis of your dental care. And because everyone has slightly different teeth and cleaning requirements, SmartSonic offers multiple cleaning modes. SmartSonic just needs 2 minutes, or 30 seconds per row, to flawlessly clean your teeth. The vibrations will alert you when it’s time to switch to the next row, meaning there’s no need to monitor anything; the toothbrush takes care of everything for you. The Niceboy ION SmartSonic lasts up to an amazing 20 days off of a single charge.
