The Colgate hum is an entry-level smart brush aimed at people who want app tracking without a flagship price. The sonic vibration is gentle, the handle is light, and the companion app gamifies brushing with coverage tracking and reminders — which can genuinely help younger users build a habit.
As a cleaning tool it is basic. The motor is weaker than premium sonic brushes, there is no adjustable intensity, and the plastic build feels its price. The app also nudges you toward buying Colgate refills. It is a fine starter brush, but most adults will outgrow it quickly.
