Colgate's connected line keeps the entry price low and puts the intelligence in the app. Sensors in the handle track where the brush has been and which zones get skipped, then the app turns that into a simple map and a points system, which works surprisingly well on teenagers. Both rechargeable and battery versions exist, three vibration modes cover normal, deep and sensitive cleaning, and replacement heads cost a fraction of what the flagship brands charge.
A reasonable first smart brush, especially for a household buying several handles at once. It will not satisfy anyone used to a pressure sensor with visual warnings or the raw plaque removal of a top oscillating model. The gamified app is the point of the product, so if notifications irritate you, most of what you are paying for goes unused.
