U-Shape Sonic Toothbrush

The Waterpik Martenit AY-681-08 uses a U-shape head that wraps around the bite to clean teeth and gums simultaneously. Sonic vibration drives bristles across surfaces in a 30-second automatic cycle. Four selectable modes cover powerful cleaning, daily care, gum massage and whitening with gel. The brush is built for home and travel use.

Wireless Charging Limits

A three-hour charge on the wireless base delivers roughly one week of brushing sessions. The 1500 mAh battery runs at 3.7 V and draws 6 W while operating. No cable connection is needed for daily recharging, but the supplied USB cable is required to power the charging base itself.

Silicone Build and Accessories

The head and body use food-grade silicone and ABS for water resistance and easy rinsing. Packaging includes four brush heads, the main handle, charging base, USB cable and manual. At 290 grams the set stays light in a washbag, and the low-battery alert helps avoid unexpected power loss.
