## What reviewers say

**Samsung Galaxy Ring** — Three whitelisted testers (Engadget, TechRadar, Tom's Guide) wore the first-gen Galaxy Ring for a week or more. All praise its light, comfortable design, ~5-7 day battery and no-subscription Samsung Health tracking. Common gripes: the $399 price, Samsung-phone/app lock-in, and thin feature set versus Oura. None ran lab-grade accuracy tests. (3 sourced reviews.)
