## What reviewers say

**ThermoWorks Thermapen ONE** — Two hands-on reviewers (Tom's Guide, 2025; Reviewed/USA Today, 2021) both rate the ThermoWorks Thermapen ONE among the fastest and most accurate instant-read thermometers they tested — roughly one-second reads and an auto-backlit display. Both flag its premium price; Tom's Guide additionally dislikes that settings are hidden behind the screwed-in rear battery panel, while Reviewed judges it only a marginal upgrade for existing MK4 owners.
