What the Philips Sonicare 3100 series 2100 HX4021/01 Rechargeable toothbrush is worth

The Philips Sonicare 2100 HX4021/01 is a rechargeable ultrasonic toothbrush powered by a built-in Lithium-Ion battery. It features a single brushing mode for daily care, delivering 31000 movements per minute across two adjustable speeds.

With a battery life of 336 h, it matches the market median (score 70/100). However, its frequency of 31000 movements per minute falls below the median (score 45/100), as does its single brushing mode against a median of 4 modes (score 45/100). The overall score stands at 53/100.
