## What reviewers say

**Philips Sonicare DiamondClean 9900 Prestige** — Only one whitelisted tester, TechRadar, published a hands-on review of this exact model. TechRadar calls it a premium, remarkably quiet 'executive' brush with helpful real-time feedback, but flags that every setting lives in the app and that its pressure sensor and location tracking trail the Oral-B iO Series 9. (1 sourced review.)

**SURI 2.0 Sustainable Electric Toothbrush** — Only one whitelisted tester, Tom's Guide, hands-on reviewed this exact SURI 2.0 model and named it an Editor's Choice for eco-conscious buyers. The reviewer praises the month-plus battery life (18 days observed on a half charge out of the box), the new pressure sensor, the sustainable aluminium body with plant-based recyclable heads, and the UV travel case and now-stable charging mount, while faulting the lack of included spare heads or mirror mounts.
