If you automatically think of CHI when you think of flat irons, you’re not alone: The brand has long been synonymous with straighteners. I still love the 2-inch CHI I’ve had for 14 years. As someone who’s at the helm of health and beauty at Reviewed, and who also happens to have a mass of thick, curly hair that I’ve been taming for years, I set out to find what makes a good flat iron, and which ones are actually worth the money.
We tested for heat adjustability, value, ease of use, safety features, button placement, cord length, and much more. To learn how we tested and selected flat irons, jump to how we tested or scroll to the bottom of the article.
The Bottom Line: A high-end flat iron that imparts serious shine.
Safety Features: Auto shut off after 1 hour
Heat Settings: Adjustable to the degree up to 410º
Ready-to-use Notification: Bars on digital screen oscillate until it’s up to temperature, then remain steady. It also has a digital screen that displays temperature.
The Details: This straightener gave my hair the mirror-smooth shine that ladies with naturally straight hair have and ladies with curly hair (hi!) crave. It has a legible screen, only took 33 seconds to reach 355º, and has a nice long cord.
This iron would have snagged our top spot, but the main downfall is its buttons: They’re rubberized and raised, making them very easy to press, which isn’t ideal since they’re positioned on the side of the iron. You will likely accidentally hit them as you’re styling. If you can be careful of them, it’s still a great pick for shiny locks.
