## What reviewers say

All three sources verified against live pages. Expect a likable app-guided experience but mediocre cleaning: Digital Trends and Engadget both found the guided-brushing app genuinely improves coverage (Engadget's self-test jumped from 49% to 98% coverage), and both liked the lightweight, well-designed body — but Digital Trends called cleaning merely superficial and Reviewed's plaque-reveal dye test left stain the Hum could not remove, with 'poor build quality' and 'short battery life' listed as cons. Rewards praise and affordability each trace to a single source. (Based on 3 reviews, 2 lab-tested, 2020-08-17–2025-08-13.)

Praised: Guided-brushing app meaningfully improves coverage and technique; Lightweight, comfortable, well-designed handle; Points-based rewards program is a clever incentive to brush more; Affordable entry point for a smart toothbrush.
Flagged: Mediocre plaque removal — superficial cleaning, failed Reviewed's plaque dye test; Cheap-feeling components: flimsy power button, unlined travel case; No true in-mouth position sensing — can be fooled by fake brushing motions; No pressure sensor to warn against brushing too hard; No charging indicator while docked; short battery life.
Disagreement: Build quality splits testers: Digital Trends said the all-plastic body feels 'lightweight and hollow' but expressed confidence it would 'hold up well over time,' while Reviewed judged the components 'poorly made.' They also diverge on cleaning severity — an 'okay job of superficially cleaning' (Digital Trends) versus performing so poorly that another toothbrush had to be used to clean the remaining plaque and dye (Reviewed).
