Our take on the Conair XL Onyx Ceramic Flat Iron

The Conair XL Onyx is a 1-inch ceramic flat iron with extra-long plates, aimed at people with long or thick hair who want to straighten more hair per pass. It heats in about 15 seconds, reaches 455°F, and offers 30 temperature settings, plus ionic and tourmaline technology for frizz control and shine. Auto shut-off and a 1.2 lb body round it out. Against salon-brand irons it trades premium build and precise heat control for broad temperature range and long plates at a value level; owners generally rate it well for everyday straightening.

Questions and answers

Is it good for thick or long hair?
Yes. The extra-long 1-inch plates let you straighten wider sections per pass, which suits long and thick hair. Very short hair can feel awkward with plates this long.
How hot does it get?
It reaches 455°F across 30 settings. Fine or damaged hair should stay in the lower range; coarse or resistant hair can use the top end.
Does it work on curly hair?
It straightens curls and waves well, but the flat plates are not shaped for making curls. Use it for smoothing, not for curling.
Does it shut off by itself?
Yes, it has auto shut-off. It still pays to unplug it after use.
What is in the box?
The flat iron itself. It does not include a heat mat or travel pouch, so plan for those separately.
How does it compare with salon-brand irons?
It offers a similar temperature range and ionic ceramic plates for less outlay, but salon brands typically have sturdier builds and more precise heat control.

At eBay, for $35.00, 46% under what the other stores charge, as of our latest check.
