Product Identity

The Bymore M306 is a black sonic toothbrush for adults who want a complete oral-care kit with long battery life. It includes eight DuPont brush heads in U-shaped and W-shaped designs for different gum and tooth needs. The handle delivers five cleaning modes and a built-in two-minute timer with 30-second pacing. An IPX7 waterproof rating handles daily bathroom moisture.

Installation & Common Issues

Charging is handled by the included USB-C cable and the rechargeable lithium-ion battery. A full charge supports up to 330 days of typical use, so frequent recharging is not required. Brush heads should be replaced when the fading reminder bristles indicate wear. The unit is designed only for oral hygiene and should not be used for other purposes.

Practical Limits

The five fixed modes — Whitening, Clean, Sensitive, Polish and Massage — define the cleaning variations available; no additional programmes can be added. Timer intervals are locked to two minutes total with 30-second quadrant prompts and cannot be customised. Battery runtime varies with the selected mode and brushing pressure, so the 330-day figure represents an upper estimate rather than a guarantee. IPX7 protection covers immersion up to one metre for 30 minutes but does not permit pressurised water or steam cleaning.

Questions about this item

How do I confirm the M306 is working correctly after first charge?

The handle vibrates when powered on, the 2-minute timer runs automatically and pauses every 30 seconds to signal quadrant changes, and the selected mode indicator stays lit during brushing.

What comes in the box and what must I purchase separately?

The box includes the black M306 handle, 8 DuPont brush heads (4 U-shaped and 4 W-shaped), a USB-C charger and built-in lithium-ion battery; no extra items are required to start brushing.

Which of the five modes should I choose for daily use?

Clean mode is the standard daily setting; Whitening adds stain-removal intensity, Sensitive reduces vibration for gentle care, Polish focuses on surface shine, and Massage stimulates gums — select the one that matches your current oral-care goal.
