Bio Ionic 10X Pro Styling Iron 1" The standout feature of this top-rated Bio Ionic 10X Pro Styling Iron 1" ($230) is definitely the vibrating plates. They help smooth a larger surface area and not tug individual strands when you're pulling the flat iron through on the first pass (versus going over and over the same section to get it sleek).
