Bio Ionic Long-Barrel Curling Iron vs Beachwaver Pro Series

Buy the Bio Ionic if your hair falls well past your shoulders and you want a long barrel that wraps the whole length in one pass. Buy the Beachwaver Pro if you want the iron to rotate for you and you style medium-length hair. The Bio Ionic reaches 430°F and has a 2-inch-longer barrel; the Beachwaver Pro goes to 450°F, heats in 30 seconds and spins left or right at a button press. Owners rate the Bio Ionic higher (4.4 from 3,196 ratings vs 4.1 from 345), and the rotating clamp on the Beachwaver takes practice and can crease hair if you release late.

• Choose the Bio Ionic Long-Barrel if you have very long hair and want a longer barrel that wraps the full length in one pass without a rotating clamp.
• Choose the Beachwaver Pro if you want the barrel to rotate for you and you style shoulder-to-mid-back hair.
