4.3 Timer da 2 minuti
The built-in 2-minute timer ensures you brush for the dentist-recommended duration. The toothbrush will briefly pause every 30 seconds to signal when to move to the next quadrant of your mouth, and will automatically turn off after 2 minutes.
4.4 Sensore di pressione intelligente
The pressure sensor helps protect your gums and teeth from excessive brushing force. It provides real-time feedback:
- Luce verde: Optimal brushing pressure.
- Luce rossa: Brushing too hard. Reduce pressure immediately.
- Luce blu: Brushing too softly. Apply slightly more pressure.

5.1 Pulizia dello spazzolino da denti
After each use, rinse the brush head thoroughly under running water. You can also detach the brush head and rinse both the head and the handle separately. Wipe the handle dry with a clean cloth.
5.2 Sostituzione delle testine delle spazzole
Dentists recommend replacing your brush head every 3 months, or sooner if the bristles become worn or frayed. The blue indicator bristles on your brush head will fade to white over time, signaling when it's time for a replacement.

The included travel case allows you to conveniently store and transport your toothbrush and up to two brush heads, keeping them hygienic and protected during travel.
