Colgate hum Smart Electric Toothbrush

Brand: hum by Colgate Smart Toothbrush

Colgate's connected sonic brush, sold as a starter kit with handle, head, charger and a hard travel case. Three vibration modes cover normal, deep clean and sensitive brushing, and the handle tracks motion, then feeds a coverage map to the hum app with points for consistent brushing. Kits usually land between 40 and 60 dollars at Walmart, which undercuts most Bluetooth brushes by a wide margin.

A reasonable choice for a teenager or an adult who needs nudging to brush the whole mouth, since the gamified scoring does its job. Two caveats: there is no pressure sensor on the handle, and Colgate has thinned the hum line out, so refill head availability varies by retailer and colour. Check that heads for the exact version are in stock before committing.
