Electronic toothbrush

The soft, flexible bristles are designed to curve around the contours of your teeth and up to 100% more stains removal from hard-to-reach spots. The sonic toothbrushes can run for more than 30 days after 2 hours charging. And led battery indicator lets you know when it's time to recharge. Also compatible with global voltage. Every electric toothbrush comes with 8 brush heads. Dentists recommend replacing toothbrush heads every 4 months so 8 will last for over 2.5 years. An auto-timer powers down automatically letting you know you've brushed for the full dentist recommended 2 minutes. And every 30 seconds interval pause coaches you to move to a new quadrant of your mouth . With IPX7 waterproof, toothbrush can be used at bath or shower, and rinse toothbrush (handle and head) under the tap to clean. Blue bristles will fade in color to remind you to replace your brush head. If the brush head is not replaced for a long time, it will hide a lot of stains, but many people often ignore it.
