## What reviewers say

**Colgate hum Smart Electric Toothbrush (Rechargeable)** — 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. (3 sourced reviews.)
