## What reviewers say

**Bio Ionic 10X Pro Styling Iron 1"** — Only one whitelisted tester, Wirecutter, hands-on panel-tested this exact model. It landed as an also-ran alternative: praised for precise, root-reaching tapered plates and a comfortable barrel, but flagged as expensive (about $200 over its budget winner) with a fingerprint-prone matte finish. Reviewed covered a different Bio Ionic and did not test it; Real Homes omitted it. (1 sourced review.)
