The Sonicare 3100 is Philips' entry-level sonic toothbrush: one Daily Care mode, 31,000 pulsations per minute and a built-in rechargeable battery. It covers the basics well, with a 2-minute timer, a pressure sensor and a brush-head change indicator, which many budget brushes leave out. It is a sensible first electric brush for anyone moving off manual brushing. Against step-up Sonicare models it gives up extra modes, a travel case and a USB charger, but it keeps the cleaning action and the pressure feedback that matter most.
