How is this different from a manual toothbrush?

The sonic motor drives high-frequency brush movements for deeper cleaning, while the soft head keeps a manual-like feel. You still brush for about two minutes.

What are the six modes for?

They set different brushing intensities and patterns, from a gentle clean for sensitive gums to a stronger clean. Most people settle on one or two.

Does it need batteries?

It is rechargeable, so you charge it instead of swapping batteries. Charge time and runtime depend on the model you receive.

Do the brush heads need replacing?

Yes. Like any electric toothbrush, the head wears down and should be replaced every few months. Check that replacement heads fit before buying.

Is it good for sensitive teeth and gums?

The gentler modes are the reason many owners pick it. Start on a low setting and move up only if your gums are comfortable.

Is it worth it over a big-brand sonic brush?

It covers the core job, high-frequency cleaning with adjustable modes, without smart features or brand support. Choose it if you want the essentials; pay more only if you want app tracking or easy parts.
