About this item Advanced Water Pulse Technology, Gentle Enough for Sensitive Gums: Delivers 1,500-2,000 pulses per minute across 4 adjustable pressure modes (50-150 PSI). Start at the lowest setting to gently flush food debris from inflamed or bleeding gums, then increase pressure as comfort improves. It helps remove food debris and reduce buildup from hard-to-reach areas compared to brushing alone-ideal for anyone whose gums bleed with traditional string floss. Rechargeable Cordless Design, 30 Days on One Charge: A single 3-hour USB charge provides approximately 30 days of daily use (one 2-minute session/day). No proprietary adapter needed-charges from any 5V USB port, laptop, or power bank. Compact enough to fit in a standard toiletry bag for business trips, vacations, or college dorms
Editor's note
The month-long battery is the selling point for me. A flosser you charge once a month is one you might actually keep using.
