Hot & Hotter All-In-One Interchangeable Hair Dryer Brush Set vs 5-in-1 Hot Air Styler Brush Set

Both are hot air styler sets with swappable heads and three heat settings. The Hot & Hotter set is the better pick for most shoppers: its three heads cover blowout volume, curls and straightening, it has a cool setting to set the style, and it runs on dual voltage for travel. The 5-in-1 set adds a dedicated smoothing comb and pre-styling nozzle and lists 1000W, but its US version is 110V only and its curling heads are air-assisted rather than a heated barrel. Owners of these brush stylers praise fast drying and easy head swaps, and complain most about bristles that snag and short cords.

• Choose the Hot & Hotter set if you want one tool for volume, curls and straightening, and you want a cool shot and dual voltage for travel.
• Choose the 5-in-1 set if you want a dedicated smoothing comb and pre-styling nozzle and you style mostly at home on US power.
