DREO Atom One review
$40–60Research-based· Last verified 2026-10-30
Verdict
A 10 in cube-shaped ceramic heater with a digital thermostat and a remote, around $50 at DREO's list price. Family Handyman and CNN Underscored both found it heats a small room, but in Family Handyman's test it took about two minutes to shut off after it was knocked over, and CNN measured 50 dB at its loudest.

Why this score: Only two independent hands-on tests so far, and both agree it heats a small room. DREO publishes dimensions and weight, but CNN measured 50 dB against the 37.5 dB claim. It also loses points for DREO's October 2026 recall of another heater, an unverified UL or ETL listing, no declared materials or warnings and a 1-year warranty.
Not hands-on tested. This score is based on public, verifiable evidence. Commissions never change a score.
