Quantitative scoring on the metrics that matter for electric toothbrushes. Higher is better.

At $279 the Philips Sonicare DiamondClean 9500 sits in the mainstream mid-tier. It covers the fundamentals that matter most for daily oral care without asking you to pay for flagship-level sensor hardware.
