## Before you buy

- The listing is inconsistent about the kit: the title and feature text claim a travel case, while the detailed set description specifies four W Optimal White brush heads, a travel case and a charger. It also calls the product 4100 Series in the title but 4000 Series in the set description. Confirm the selected model and included items before purchase. The 21-day claim is for regular brushing, with the description specifying two minutes twice daily on standard mode.

- Buyers seeking more than two brushing modes, which are not listed for this model.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller one-star share indicates that experiences are not uniformly favourable. Without review comments, the reasons for those ratings are unknown. Treat the scores as a broad signal rather than evidence about the pressure sensor, timers or claimed battery runtime.
