Overview
The Hot Tools Black Gold Ionic is a 1 1/4 inch flat iron with rounded edges and 27 digital heat levels reaching 455°F, marketed for both straightening and curling or waving with the same tool.
Hot Tools frames the Black Gold finish as inspired by gold's even heat properties, paired with a micro-shine coating. The 27-level digital heat range is unusually granular for a flat iron, giving finer control than the typical handful of dial settings, and the rounded plate edges are meant to double as a curling surface.
- 1 1/4 inch floating ceramic plates
- 27 digital heat levels up to 455°F
- Rounded edges for curling and waving
- Universal dual voltage, 2-hour auto shutoff
Who it's for
Good for people who want fine-grained heat control across a wide range, from low settings for fine hair up to 455°F for coarse or resistant hair. Also suits anyone who wants one tool for both straight and curled looks rather than a separate curling iron.
Pros and cons
- 27 heat levels for fine temperature control
- Rounded plates can curl or wave, not just straighten
- Universal dual voltage for travel
- 2-hour auto shutoff
- 1 1/4 inch width is a middle ground, not ideal at either extreme of hair length
Performance notes
The 27 digital heat levels let users step up gradually rather than jumping between a handful of fixed settings, useful for finding the lowest effective temperature for a given hair type. Floating 1 1/4 inch plates with rounded edges are designed to glide without snagging while still holding a curl shape when the iron is rotated. Universal dual voltage and a 2-hour auto shutoff round out the safety features.
