What to know
The Sonicare 4100 focuses on the features that matter most when moving from a manual brush: paced timing, a two-minute session, and feedback when too much pressure is applied. Two intensity settings can make the transition less abrupt, while the slim handle is simpler than app-connected premium models. The charging setup uses USB and may not include a wall adapter, so check what you already own. It is a sensible fit for someone who wants structured brushing without paying for a screen, travel charging case, or extensive mode selection.
