The Philips Sonicare DiamondClean Smart 9700 and the Fairywill Sonic Power represent two distinct approaches to electric toothbrushes available to consumers. The Philips Sonicare DiamondClean Smart 9700 pairs a well-known premium brand with an app-connected tracking system, pressure sensors. And multiple brushing modes that aim to deliver guided feedback on coverage and technique. In contrast, the Fairywill Sonic Power relies on a simpler sonic motor, offers a more compact charging case. And sells at a fraction of the flagship price while still providing multiple intensity levels and a two-minute timer. Public reviews and manufacturer specifications highlight the Philips model's longer battery claims and brush-head subscription options against the Fairywill's emphasis on portability. And straightforward daily use, yet both lack extensive independent clinical data that would allow direct performance comparisons. The short version: choose the Philips Sonicare DiamondClean Smart 9700 for its smart coaching features or the Fairywill Sonic Power for lower cost. And smaller footprint, but consider other models if independent test results are a priority.

Verdict: Pick Philips Sonicare DiamondClean Smart 9700 if you want premium brand features and smart brushing feedback; pick Fairywill Sonic Power if you prioritize a lower price and compact size; skip both if you need detailed published performance specifications.

Philips Sonicare DiamondClean Smart 9700 lists at $199.99 while Fairywill Sonic Power lists at $39.99 — Fairywill Sonic Power undercuts Philips Sonicare DiamondClean Smart 9700 by $160 (400%).
