1Sonic vibration

The head vibrates fast enough to push water and toothpaste between teeth. You guide it rather than scrub.

The charger is a glass, so it looks tidy on the sink. Stand the brush in it to charge.

It charges inside the case, so trips do not need a separate charger.

Every three months is the usual advice, and Coupang sells replacement heads as well.
