What to know before buying

Listing details to confirm

Listing details are inconsistent: the title identifies a 4100 Series HX4046/52, while the set description calls the brush a 4000 Series. Battery power is listed alongside a rechargeable claim, and dimensions and weight appear in differing formats. Confirm the selected listing's exact model and kit contents. The up-to-21-day runtime is conditional on the stated standard-mode routine.
