What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 1 lab-tested.)
Praised: Remarkably quiet, premium 'executive' design that feels smooth and comfortable in the hand; Real-time feedback that warns on scrubbing and auto-lowers intensity when you press too hard; USB-C rechargeable leather-effect travel case, practical for frequent travellers.
Flagged: No handle controls beyond a power button — all mode/intensity changes require the app; Pressure sensor and in-app location tracking trail the Oral-B iO Series 9; Expensive at $399.99 launch price.
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. (1 sourced review, 1 lab-tested.)
Praised: Month-plus battery life (18 days observed on a half charge out of the box); New pressure sensor is a welcome improvement over the original; Sustainable aluminium body with plant-based recyclable heads and premium design.
Flagged: No replacement heads or spare mirror mounts included in the box; $10 pricier than the original at $135 / GBP 105; Existing Suri 1.0 owners don't need to upgrade.
