Is $39.99 a good price for this flat iron?

Yes. It usually sells for around $60–$80 new, so $39.99 at eBay as of November 4, 2026 is a strong discount. Check that the listing is new and sealed, since used and open-box units also circulate.

Is it good for thick or curly hair?

The 440°F top setting and titanium plates handle thick and coarse hair well. Use the higher settings and section hair thinly for best results.

Can it be used outside the US?

Yes. It has dual voltage, so it works with a plug adapter abroad. You may still need a converter in countries with different outlet types.

Does it work as a curler?

Yes. The rounded body lets you wrap hair to make waves and curls, which is the volume part of the 3-in-1 design. It is not a substitute for a dedicated curling iron on very long hair.

The flat iron and its original packaging. No heat mat or pouch is listed as included.

Prices dip during Black Friday, holiday sales and Amazon Prime events. At $39.99 it is already near the low end of its range.

Our take on the Kristin Ess 3-in-One Professional Titanium Hair Straightener

The Kristin Ess 3-in-One Professional Titanium Hair Straightener is a 1¼-inch flat iron with titanium plates, ceramic body and ionic technology. It reaches 440°F across four heat settings and heats up almost instantly, and the rounded barrel lets you straighten, curl and add volume with one tool. It has auto shut-off and dual voltage for travel. At $39.99 at eBay as of November 4, 2026, it sits well below the brand's usual $60–$80 retail, and four stores list it new.
