(checked 2026-10-10)Small sample (108 ratings). The Amazon listing is titled 'FlexStyle Next-Gen IonCurl 5-in-1 (HD840)'. I assume it is the model CNN tested, but CNN does not give a model number.
Shark's 2026 FlexStyle, CNN Underscored's top multi-styler. Its curlers grip thick hair much better than the original's. It is new, with little owner feedback, has no storage case, and its frizz attachment disappointed testers.
Top complaints
- No storage case
CNN Underscored notes it comes without a pouch or case; Shark sells one for $60.

One CNN tester saw no difference from the FrizzFighter, and the other said it made her wiry flyaways more noticeable.

What owners love

CNN found the automatic temperature mode kept the scalp comfortable during rough-drying.
Source: CNN Underscored - Powerful, versatile oval brush
CNN rated it one of the most powerful and versatile tools tested. The oval brush smoothed frizz while adding volume.
