What reviewers say

Hot Tools Pro Artist Black Gold 1" Flat Iron
Only Reviewed (USA Today) hands-on-tested this exact Hot Tools HT7122BG Black Gold flat iron, naming it Best Overall in its 2026 flat-iron guide. Tester Jessica Kasparian praised the ~14-second heat-up, sleek frizz-free results with little visible damage, the audible ready-chime, the long 4.25-inch plates and nine-foot cord, and the wide 205–455°F range in precise 10-degree increments, and listed no cons. (1 sourced review, 1 lab-tested.)
Praised: Sleek, frizz-free, shiny results with little visible damage; Fast ~14-second heat-up time; Audible chime/beep when target temperature is reached.
Flagged: Reviewed found no downsides for this iron (Cons listed as 'None that we could find').
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, 1 lab-tested.)
Praised: Tapered, angled 1-inch ceramic plates straighten precisely and reach into the roots while still gripping larger sections; Thin barrel is comfortable to hold and the matte casing feels luxe with a bit more heat protection than rivals; Vibration mode let several testers finish in far fewer passes without any snagging or grabbing.
Flagged: Expensive; testers doubted the extras justified roughly $200 over the budget winner; Matte finish is prone to stubborn greasy fingerprints after use with styling products; Vibration mode is unintuitive and initially confused panel testers.
