Philips HX684B is an electric toothbrush handle designed for superior plaque removal and gum health. It features advanced sonic technology, multiple cleaning modes (Clean, White+, Gum Health, Deep Clean), a pressure sensor, and BrushSync technology to track brush head life. This one doesn’t seem to charge. I am including another black toothbrush handle but serial number has smudged off, the battery is still rechargeable. I can include a charger and carrying case if interested.
